A hydrogel containing a crosslinked product of a vinyl alcohol polymer having an ethylenically unsaturated group and a carboxy group and a bioactive substance having an amino group, the carboxy group of the crosslinked product and the amino group of the bioactive substance being covalently bound via an amide bond.
A61K 47/58 - Medicinal preparations characterised by the non-active ingredients used, e.g. carriers or inert additivesTargeting or modifying agents chemically bound to the active ingredient the non-active ingredient being chemically bound to the active ingredient, e.g. polymer-drug conjugates the non-active ingredient being a modifying agent the modifying agent being an organic macromolecular compound, e.g. an oligomeric, polymeric or dendrimeric molecule obtained by reactions only involving carbon-to-carbon unsaturated bonds, e.g. poly[meth]acrylate, polyacrylamide, polystyrene, polyvinylpyrrolidone, polyvinylalcohol or polystyrene sulfonic acid resin
The present invention relates to a multilayer structure for storing or transporting a gas comprising hydrogen, wherein the multilayer structure comprises at least three layers comprising an inner layer comprising at least one first polymer, a middle layer comprising ethylene-vinyl alcohol copolymer, and an outer layer comprising at least one second polymer, and wherein the water-vapour transmission rate of the inner layer is lower than that of the outer layer. The multilayer structure has excellent hydrogen gas barrier properties. Therefore, the multilayer structure is suitable for a hydrogen storage vessel and a hydrogen transportation pipe.
