Method for obtaining biodegradable polymers that has a stage of esterification and/or transesterification and amidation reaction, a stage of prepolycondensation, a stage of polycondensation, a stage of extraction and a stage of drying, eliminating the use of chain extenders. The polymer can achieve all the range of viscosities desired and with an improved colour compared to the polymer from other methods, where chain extenders are used, provide a more efficient process, that is environmentally cleaner and safer for the operatives.
Method for obtaining biodegradable polyesteretheramide that has a stage of esterification and/or transesterification and amidation reaction, a stage of prepolycondensation, a stage of polycondensation, an optional stage of extraction, a stage of drying and a final stage of extrusion with additives. The method of obtaining PEEA enables better satisfaction of the needs of each client as regards viscosity, composition and additives. It enables reducing the amount of interface product that has lower commercial value and improves the colour of the product, while at the same time provides a more efficient process, ecologically cleaner and safer for all the operatives.
The invention relates to a method for obtaining biodegradable polymers, which comprises a step of performing esterification and/or transesterification and/or amidiation, a step of performing pre-polycondensation, a step of performing polycondensation, a step of extracting and a step of drying, thereby dispensing with the use of chain extenders. The main advantage of the method is that the polymer thus obtained can be produced in the entire desired range of viscosities and with an improved colour in comparison with polymers obtained by means of other methods using chain extenders, all with a method that is more efficient, more ecological, cleaner and safer for the operator.
The invention relates to a method for obtaining biodegradable polyesteretheramide (PEEA), which comprises a step of performing esterification and/or transesterification and amidiation, a step of performing pre-polycondensation, a step of performing polycondensation, an optional step of extracting, a step of drying, and a final step of extruding with additives. The main advantage of the invention with respect to patent EP 2628761 is that this method of obtaining PEEA allows the needs of each client to be better satisfied in relation to viscosity, composition and additives, and allows the quantity of interface product, which has a lower commercial value, to be reduced and the colour of the product to be improved. All this is achieved with a method that is more efficient, more ecological, cleaner and safer for the operator.
Pigments and inks for the decoration of ceramic objects, which have, in their formulation, iron and phosphorus oxides, combined with lithium oxide, the presence of this latter element being that which gives the pigments the capacity of being milled (in the form of a suspension in a solvent base) to the point of being able to obtain inks that are characterized by having very narrow PSD and an upper bound of less than 1 μm. Thanks to this PSD, inks prepared using these pigments can be applied in standard printing heads to glazed ceramic objects, enabling a metallic gloss and appearance to be obtained after said ceramic objects undergo a firing process. The ink obtain has a low viscosity, allowing an increase in the concentration of the pigment and thus an increase in its yield, optimizing gloss and the metallic appearance of the finished ceramic objects.

Opaque single-layer bottle with light protection and production method thereof
Single-layer plastic container with inorganic light-shielding fillers provides a strong light shield, including near-total shields blocking the whole light spectrum, in a light weight container. The plastic container contains at least two different thermoplastic polymers that functionally complement each other. Light-shielding inorganic fillers contain at least two different inorganic substances that complement each other in their light-shielding function. The plastic compositions achieve light shielding in very light single-layer containers without the cost and complexity of multi-layer structures. Only conventional equipment and production processes are required.

Bio-based and biodegradable polymer of the type used in the manufacture of films and injected or molded products, for example, for applications of containers, bags, healthcare products and films for agriculture or other applications in which the biodegrading characteristic is of interest, has a biodegradable polymer, thermoplastic starch in the co-continuous or continuous phase and at least one polymer that comes from a stable dispersion of the polymer in water or latex. This increases the thermoplastic starch content and thus decreases the biodegradable polymer and obtains films of a greater width by blow extrusion, with similar tensile properties. This provides the added advantage of a lower cost in raw materials, less impact on the environment and greater production.
A biodegradable polyesteretheramide for manufacturing films and molded products, for example for application in the protection of foodstuff products and films for agriculture, contains a compound with at least 3 groups capable of reacting with one or several types of the active groups present in the reaction mixture, that is, compounds which, while containing ether groups in their structure, have active groups capable of reacting in the reaction mixture to form amide groups, and which simplifies and shortens the preparation process, reducing its economic cost and obtaining products of greater transparency and higher strain at failure, while maintaining other properties such as resistance to tearing and puncture, and allowing greater widths of films to be made with smaller thicknesses.
A process for the additivation of synthetic fibers, artificial fibers and polymers conferring special properties to them, the process comprising the following steps: the encapsulation of an additive in the pores of a porous material; the incorporation of particles of the porous material (capsules) into the polymer matrix of the fiber; and spinning of the fiber; the capsule withstanding the temperatures and other conditions of the different manufacturing processes which the fibers might undergo and the introduction of the additive into the polymer matrix thereof, characterised in that the porous material is a metal oxide, a zeolite, an aluminophosphate, clay, a carbon material, a hybrid organic-inorganic material or a porous polymer. The invention is an improvement in the additivation process of fibers and polymers in terms of the nature of the capsules used, the increase in the storage capacity of additives thereof, the process of incorporating the capsules into the polymer matrix of the fibers and the fact that the present invention refers to an industrial process.
