ABSTRACT:
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.
