Abstract: Glycerol fatty acid esters of C12-C24 fatty acids which may have one hydroxyl group and from 1 to 3 carbon-carbon double bonds are used as an additive for molding compositions based on poly-C2-C6-alkylene terephthalates.The thermoplastic molding composition comprises, based on the total of components A and B and, if present, C to E, which together give 100 % by weight,a) as component A, from 40 to 99.99% by weight of at least one polyester based on poly-C2-C6-alkylene terephthalates,b) as component B, from 0.01 to 3% by weight of glycerol fatty acid esters of C12-C24 fatty acids which may have a hydroxyl group and from 1 to 3 carbon-carbon double bonds,c) as component C, from 0 to 49.99% by weight of blend polymers miscible with component A or dispersible therein,d) as component D, from 0 to 50% by weight of fillers, ande) as component E, from 0 to 10% by weight of other usual additives.

Abstract: The invention concerns a process for preparing compositions containing at least one thermoplastic polymer A and at least one polyamide B by dissolving the thermoplastic polymer A in at least one lactam b and optionally further polyamide-forming monomers b, and subsequent polymerization of the monomers b. The monomers b are polymerized in the presence of between 0.001 and 5 wt % water, relative to the monomers b.
