摘要：
Copolymers suitable for use as temporary surface protection for two- or three-dimensional structures and as sizing agents are based on C.sub.1 -C.sub.8 -alkyl acrylates and/or methacrylates and are obtainable by free radical emulsion or solution polymerization ofA) from 50 to 95% by weight of a C.sub.1 -C.sub.8 -alkyl acrylate or methacrylate,B) from 5 to 20% by weight of an unsaturated carboxylic acid or anhydride,C) from 0 to 20% by weight of further water-soluble comonomer, andD) from 0 to 10% by weight of other comonomer in the presence ofE) from 2 to 60 parts by weight of a polyvinyl alcohol per 100 parts by weight of the monomer mixture of A) to D).
