Abstract: The invention relates to a process for the coating of electrically conducting substrates in which(1) the substrate is immersed in an aqueous electrocoating paint comprising at least one cathodically depositable resin,(2) the substrate is connected as cathode,(3) a film is deposited on the substrate using direct current,(4) the substrate is removed from the electrocoating paint and(5) the deposited paint film is baked.In this invention an electrically conducting substrate coated by a coating produced by plasma polymerization is employed as substrate.

Abstract: Molding materials containing styrene-acrylonitrile copolymers, in which an additional essential ingredient is from 0.1 to 2.0% by weight, based on the copolymer, of a three-block polymer X-Y-X, where X is a terminal ethylene oxide block and Y is a central propylene oxide block. The proportion of terminal ethylene oxide blocks X, based on block copolymer, is from 5 to 20% by weight, while the central propylene oxide block Y has a number-average mean molecular weight of from 700 to 3,000 and its proportion is from 80 to 95% by weight, based on block copolymer. The number-average molecular weight of the sum of the two terminal blocks X is from 140 to 1,000.
