Abstract:
The present invention relates to a polyester mixture containing: i) 95 to 99.95 wt%, relative to components i and ii, of a polyester selected from the group consisting of: polybutylene terephthalate polycyclohexylenedimethylene-2,5-furandicarboxylate, polybutylene adipate-co-terephthalate, polybutylene sebacate-co-terephthalate, polybutylene succinate-co-terephthalate, polybutylene-2,5-furandicarboxylate-co-succinate, polybutylene-2,5-furandicarboxylate-co-adipate, polybutylene-2,5-furandicarboxylate-co-azelate, polybutylene-2,5-furandicarboxylate-co-sebacate, polybutylene-2,5-furandicarboxylate-co-brassylate, polybutylene-2,5-furandicarboxylate-co-1,18-C 18 -dicarboxylate, polybutylene succinate, polybutylene adipate, polybutylene succinate-co-adipate, polybutylene succinate-co-sebacate, polybutylene sebacate or mixtures of 2 or more of the specified polyesters and ii) 0.05 to 5 wt%, relative to components i and ii, polyethylene-2,5-furandicarboxylate.
Abstract:
The invention relates to thermoplastic molding compounds containing A) 30 to 99.99 wt.% of a polyester made of 50 to 100 wt.% of at least one polyalkylene terephthalate A1), with respect to A), and 0 to 50 wt.% of a polyester A2), which is different from A1, B) 0.01 to 2 wt.% of a acrylic acid polymer, made of B1) 70 to 100 wt.% acrylic acid and B2) 0 to 30 wt.% of at least one other ethylenically unsaturated monomer which can be co-polymerized with acrylic acid and which is selected from the group of mono-ethylenically unsaturated carboxylic acids, and C) 0 to 70 wt.% of other additives, wherein the sum of the weight percentages of the components A) to C) equals 100%.
Abstract:
The invention relates to a method for producing a composition comprising (A) at least one lactam; (B) at least one catalyst; (C) an activator from the group consisting of isocyanates, acid anhydrides, acid halogenides, the reaction products thereof with (A), and the mixtures thereof; and (D) at least one polyethylenimine. The invention likewise relates to a composition comprising (i) 0.01 to 10 wt.%, based on the sum of the components (A) and (D), of at least one polyethylenimine; and (ii) 90 to 99.99 wt.%, based on the sum of the components (A) and (D), of at least one lactam (A) and/or a polyamide that can be obtained from (A).
