ABSTRACT:
Molding compositions based on polyvinyl chloride contain as the component imparting impact resistance homo- and copolymeric acrylic acid esters of oxethylates of phenol or of substituted phenols, wherein the difference of the indices of refraction n.sub.D.sup.20 (at least 20.degree. C., measured with the Na D line) between the basic polymer and the component imparting impact resistance at most is .+-.0.01; optionally copolymers with other acrylic acid esters can also be used in the molding compositions. The latter are inexpensive to manufacture and, besides transparency and weatherability, also have impact resistance.
