Multistage graft copolymer and its use for the preparation of

A lubricant for shaping polyvinyl chloride, which contains esters of oligomers of trihydric, tetrahydric, pentahydric or hexahydric aliphatic alcohols, having 3 or more monomer units, with saturated or unsaturated C.sub.8 -C.sub.36 -fatty acids, from 30 to 100% of the alcoholic hydroxyl groups being esterified.

Lubricants for shaping polyvinyl chloride, which contain esterified

Mixtures based on vinyl chloride polymers and small amounts of a copolymer of an ester of acrylic acid or methacrylic acid. The said copolymer contains acrylic acid ester or methacrylic acid ester units, units which contain a lactone ring structure, and, optionally, units of other copolymerizable monomers. The mixtures exhibit improved processability and may in particular be used for the manufacture of films, sheets and the like.

Thermoplastic vinyl chloride polymer compositions with improved

Mixtures based on vinyl chloride polymers and small amounts of copolymer of an ester of acrylic acid or methacrylic acid, which mixtures have been obtained by polymerization of vinyl chloride in the presence of the above copolymer. The said copolymer contains acrylic acid ester or methacrylic acid ester units, units which contain a lactone ring structure, and, optionally, units of other copolymerizable monomers. The mixtures exhibit improved processability and may in particular be used for the manufacture of films, sheets and the like.
