Abstract: A process for the continuous preparation of copolyamides in which (a) an aqueous solution of salts comprising equimolar amounts of diamines and dicarboxylic acids is passed under elevated pressure with simultaneous evaporation of water through a tubular precondensation zone to form a vapour phase and a prepolymer, at a temperature above the melting point of the prepolymer, (b) the vapour phase is separated from the prepolymer melt, (c) the vapour phase is separated in a column into steam and an aqueous diamine solution, and the diamine-containing aqueous solution is fed back into the polymerisation, (d) the prepolymer melt is mixed with molten caprolactam at polyamide-forming temperatures and (e) the mixture of prepolymer and caprolactam is passed from top to bottom through a vertical polymerisation tube at polyamide-forming temperatures, and a copolyamide is obtained.

Abstract: Novel nylon molding materials having high impact strength contain, as an additive, a copolymer of ethylene, a primary or secondary C2-C8-alkyl acrylate or methacrylate and a monomer possessing a (latent) acid functional group, in particular an ethylene/n-butyl acrylate/acrylic acid copolymer.

Abstract: Elastomeric thermoplastic molding materials contain (A) from 5 to 50 parts by volume of a partially or completely crystalline thermoplastic polymer having a melting point of above 160 DEG C., as a coherent phase, and (B) from 95 to 50 parts by volume of one or more crosslinked elastomeric polymers which are prepared by emulsion polymerization, are dispersed in the component A and have a glass transition temperature Tg of below -10 DEG C., the sum of A and B being 100 parts by volume, with the proviso that the mixture of A and B has a Vicat softening temperature, measured according to DIN 53,460, which is 5 DEG -40 DEG C. lower than that of the component A, with or without (C) effective amounts of conventional assistants.
