Moulding composition

摘要

The invention relates to a moulding composition which is a mixture of two polymers A and B of vinyl chloride. Polymer A is a homopolymer or copolymer of vinyl chloride having a K value of from 55 to 65 and makes up from 99.9 to 95 % by weight of the moulding composition. Polymer B is present in a proportion of from 0.1 to 5 % by weight and is prepared in emulsion by a batch process, has a mean particle diameter (d50 value of the primary particles) of 0.02 to 1.0 mu m and has a K value of from 75 to 90. The moulding composition may contain conventional graft copolymers based on crosslinked or uncrosslinked rubbers or additives and is used for the production of films.
