1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL, SE) Polymer of vinyl chloride grafted onto a copolymer of ethylene and vinyl acetate containing from 0.5 to 7% by weight of a copolymer of ethylene and vinyl acetate comprising from 20 to 50% by weight of vinyl acetate, characterized in that the intrinsic viscosity of the copolymer of ethylene and vinyl acetate, measured at 20 degrees C in m-xylene is between 0.05 and 0.10 l/g. 1. Claims (for the Contracting State AT) Rigid compositions based on a polymer of vinyl chloride grafted onto a copolymer of ethylene and vinyl acetate containing from 0.5 to 7% by weight of a copolymer of ethylene and vinyl acetate comprising from 20 to 50% by weight of vinyl acetate, characterized in that the intrinsic viscosity of the copolymer of ethylene and vinyl acetate, measured at 20 degrees C in m-xylene, is between 0.05 and 0.10 l/g and in that they comprise a reinforcing acrylic copolymer consisting of a polymer of methyl methacrylate grafted onto an elastomer of alkyl acrylate in which the alkyl groups contain from 2 to 10 carbon atoms.
