Abstract:
Copolymers obtained by free-radical polymerization of a mixture of a) 80 to 99% by weight of a monoolefinic monomer selected fronm the group consisting of acrylic monomers, methacrylic monomers and N-vinyllactam monomers (monomers a)), b) 1 to 20% by weight of a monoolefinic silane monomer (monomer b)), with the proviso that the total of components a) and b) equals 100% by weight,
