Abstract: The invention relates to a moulding composition which is a mixture of a graft copolymer A and PVC. The graft copolymer A makes up 70-95 % by weight of the moulding composition and contains a monomer from the group consisting of vinyl aromatic monomers and the group consisting of ethylenically unsaturated monomers, grafted on to a rubber from the series consisting of polybutadienes, polyacrylates or EPDM. Component B is present in the moulding composition in a proportion of 5-30 % by weight and is a polymer of vinyl chloride prepared by a batch method and having a Fikentscher K value of 75-90 and a mean particle diameter (primary particles) of a) 0.02-1.0 mu m (emulsion polymer) or b) 0.1-2.0 mu m (micro suspension polymer). The moulding composition may additionally contain conventional additives and is used for the preparation of mixtures with polyvinyl chloride.

Abstract: A vinyl chloride emulsion polymer (I) esp. for film prepd. according to the Luvitherm process contains 0.5-5 wt. % graft copolymer (II) as processing aid. (II) comprises (a) 30-80 wt.% elastomeric polymer as the backbone with a Tg 0 degrees C and contains >=15 wt.% (w.r.t. the elastomeric backbone) conjugated diene and (b) 70-20 wt.% 1-4C alkyl methacrylate and/or monovinyl aromatic cpd. and opt. other comonomers. The PVC may be processed more rapidly into a film. The films have good gloss and smoothness and may be used as adhesive or magnetic recording tapes.

Abstract: 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.

Abstract: A moulding composition comprising bulk or suspension PVC (A) and microsuspension (PVC) (B). Component 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. Component B is a polymer of vinyl chloride which is present in a proportion of from 0.1 to 5 % by weight and is prepared in suspension by a batch process, has a mean particle diameter (d50 value of the primary particles) of 0.1 to 2.0 mu m and has a K value of from 75 to 90. The moulding composition may additionally contain conventional graft copolymers based on crosslinked or uncrosslinked rubbers and conventional additives and is used for the production of films.
