Copolymer solution based on tertiary butyl acrylate, tertiary butyl methacrylate or mixtures thereof

摘要

Copolymers based on tert-butyl acrylate and/or tert-butyl methacrylate, having a K value of from 10 to 50 and obtainable by free radical polymerization of A) from 20 to 90% by weight of tert-butyl acrylate and/or tert-butyl methacrylate, B) from 10 to 60% by weight of N-vinylpyrrolidone and C) from 0 to 30% by weight of a C1-C20-alkyl acrylate, a C1-C20-alkyl methacrylate, a C2-C4-hydroxyalkyl acrylate, a C2-C4-hydroxyalkyl methacrylate or vinyl acetate or a mixture thereof, are used as film formers in hair setting compositions and compositions for the surface protection of two- or three-dimensional structures.
