A) 50 bis 95 Gew.-% eines C₁-C₈-Alkylacrylates und/oder -methacrylates, B) 5 bis 20 Gew.-% einer ungesättigten Carbonsäure und/oder eines ungesättigten Carbonsäureanhydrids, C) 0 bis 20 Gew.-% weiterer wasserlöslicher Comonomerer und D) 0 bis 10 Gew.-% sonstiger Comonomerer in Gegenwart von E) 2 bis 60 Gew.-Teilen Polyvinylalkohol, pro 100 Gew.-Teile des Monomerengemisches aus A) bis D). Copolymers based on C₁-C₈ alkyl acrylates and / or methacrylates, obtainable by radical emulsion or solution polymerization of A) 50 to 95% by weight of a C₁-C₈ alkyl acrylate and / or methacrylate, B) 5 to 20% by weight of an unsaturated carboxylic acid and / or an unsaturated carboxylic anhydride, C) 0 to 20% by weight of further water-soluble comonomers and D) 0 to 10% by weight of other comonomers in the presence of E) 2 to 60 parts by weight of polyvinyl alcohol, per 100 parts by weight of the monomer mixture from A) to D). n n n The products are used as a means of temporarily protecting the surface of flat or spatial structures and as a sizing agent. |
