Abstract

Vinyl chloride copolymers of (a) from 60 to 78 parts by weight of vinyl chloride, (b) from 1 to 20 parts by weight of glycidyl methacrylate and (c) from 12 to 40 parts by weight of compounds copolymerizable with (a) and (b) have viscosity values, measured in 20% strength by weight toluene solution at 23.degree. C., of from 10 to 100 mPa.s.
