    IPC: C08J9/36

    Abstract: Polybutylene terephthalate can be used as a gas diffusion barrier for closed-cell rigid polyurethane foams. A thermal insulation element containing a closed-cell, rigid polyurethane foam, which is at least partially covered by a layer system containing at least one layer formed by a polybutylene terephthalate composition, is useful. Articles and devices may contain a corresponding thermal insulation structure, such as refrigerators, insulation panels, pipe insulations, water heaters, and thermally insulated transport boxes.

    Abstract: Thermoplastic mixtures comprising: A) 30% to 100% by weight of a thermoplastic blend consisting of: A-1) 65% to 75% by weight of a polyester, A-2) 5% to 25% by weight of an HD or LD polyethylene, A-3) 3% to 10% by weight of an ionomer composed of at least one copolymer of: 3-1) 30% to 99% by weight of ethylene 3-2) 0% to 60% by weight of one or more compounds selected from the group consisting of 1-octene, 1-butene and propylene and 3-3) 0.01% to 50% by weight of one or more functional monomers selected from the group consisting of carboxylic acids, carboxylic anhydrides and carboxylic esters with the proviso that the proportion of carboxylic acids is 30% to 100% by weight, the proportion of carboxylic anhydrides and/or carboxylic esters is complementarily 0% to 70% by weight and the hydrogen of the carboxyl groups of the carboxylic acids is replaced by a metal selected from the group consisting of sodium, potassium and zinc in a proportion of at least 20% (“mol %”) of the total number of carboxyl groups, wherein the proportions of components 3-1, 3-2 and 3-3 sum to 100% by weight, A-4) 0.5% to 5% by weight of an epoxidized oil or oil mixture, in which the at least partially unsaturated fatty acids in the underlying fatty acid esters of the oil or oil mixture have 12 to 22 carbon atoms, wherein the proportions of components A-1, A-2, A-3 and A-4 sum to 100% by weight of component A), B) 0 to 70% by weight of further additives, wherein the proportions of components A) and B) sum to 100% by weight.
