Process for rendering mixtures comprising at least one vinyl chloride-based resin and at least one olefin-based resin compatible
First Claim
1. Process for rendering mixtures comprising at least one vinyl chloride-based resin and at least one clefin-based resin compatible, characterised by producing a mixture which comprises from 50 to 95% by weight of at least one vinyl chloride-based resin, from 1 to 20% by weight of at least one olefin-based resin, from 1 to 20% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 10 and 35% and from 2 to 40% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 60 and 95%.

Abstract
A mixture is produced, comprising from 50 to 95% by weight of at least one vinyl chloride-based resin, from 1 to 20% by weight of at least one olefin-based resin, from 1 to 20% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 10 and 35% and from 2 to 40% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 60 and 95%, and the product thus obtained is then processed.
The process makes it possible in particular to produce sheets which have good mechanical properties and which have a remarkable transparency.
