Repulpable moisture vapor barriers are disclosed. The moisture vapor barriers are essentially devoid of wax, and include a resin latex and an un-modified component having a crystalline platelet structure. The compositions can optionally include a hydrophobic component other than wax. Suitable resin latexes include polystyrene, styrene-acrylonitrile, styrene-acrylonitrile-butadiene, styrene acrylates, styrene-butadiene, carboxylated styrene butadiene, polyvinyl chloride, polyvinyl acetate, waterborne polyurethanes, alkyl acrylates, polyvinylidene chloride, ethyl vinyl chloride, and copolymers and terpolyrners thereof. The component having a crystalline platelet structure can be suspended in means for suspending the component, such as fully hydrolyzed polyvinyl alcohol.

The present invention provides a composite insulation material. The material includes a layer of an insulation, such as foam or fiberglass, and a paper layer. The paper layer is coated with a moisture vapor barrier, using a coating composition that includes a resin latex and a component having a crystalline platelet structure. Suitable resin latexes include poly(meth)acrylates, carboxylated or non-carboxylated butadiene-acrylonitrile, polystyrene, styrene-acrylonitrile, styrene-acrylonitrile-butadiene, styrene acrylates, styrene-butadiene, carboxylated styrene butadiene, polyvinyl chloride, polyvinyl acetate, waterborne polyurethanes, vinyl acrylics, polyvinylidene chloride, ethyl vinyl chloride, vinyl acetate- ethylene copolymers, and copolymers, terpolymers, and blends thereof. A suspending agent for the crystalline platelet component can be present, and is typically a hydrophilic polymer. The coating compositions can include wax, or can be essentially devoid of wax. A hydrophobic agent other than wax can optionally be added. The crystalline platelet structure can be unmodified, or modified to increase its hydrophobicity. The composite material can also be in the form of a foil/scrim/Kraft paper laminate, which can be combined with a layer of insulation if desired. The insulation materials can be used, for example, to insulate pipes and ductwork, or other aspects of buildings.

The present invention provides a polymer composition capable of being cured or crosslinked in the absence of conventional sulfur and accelerator cure systems. The polymer is formed from olefinically unsaturated monomers and includes at least one conjugated diene monomer. Such polymer includes additional functionality provided by a monomer which may crosslink via enamine formation, condensation with aldehydes, Michael addition, alkylation with alkyl halides, reaction with diisocyanates, or reaction with melamines. By these same mechanisms, the polymer may additionally or alternatively be reacted with a substrate, such as a fiber, to bind the polymer to the substrate. Further, the polymer may be reacted with a molecule, such as a plasticizer, dye, indicator, surface modifier, or antimicrobial moiety in order to bind the molecule to the polymer. Methods of making articles of manufacture that comprise the polymer compositions of the invention are also disclosed.

Leather composites and methods of making that include engineered leather substrates or composites are disclosed. The substrate includes leather, non-leather fibers, a binding agent and can further include cushioning agents, softeners, processing aids, and colorants. A composite can include the substrate and one or more additional layers, such as top coat layers, reinforcing layers, and cushioning layers. The substrate and or the composite can be chemically or mechanically embossed. The leather used to form the engineered leather substrate can be derived from post- industrial and/or post-consumer materials. The non-leather fibers can be organic or inorganic, and the composition can also include inorganic fillers, such as calcium carbonate, and clays. The cushioning agents can include polymeric microbubbles, foam, rubber particles, and other low density cushioning agents. The binding agents can be synthetic or natural, such as synthetic latex, natural latex, PVA, and starch.
