Abstract: CRYSTAL CLEAR MOULDING COMPOSITIONS OF HIGH IMPACT STRENGTH COMPRISING (A) A GRAFT COPOLYMER OF VINYL CHLORIDE AND AN ELASTOMER CONSISTING OF AT MOST 90% BY WEIGHT OF BUTADIENE OR ANOTHER CONJUGATED DIOLEFIN AND AT LEAST 10% BY WEIGHT OF COMONOMERS PART OF WHICH ARE COMONOMERS WHOSE HOMOPOLYMERS HAVE HIGHER REFRACTIVE INDICES THAN POLYVINYL CHLORIDE WHILE THE OTHER PART IS MONOMERS THAT IMPROVE THE COMPATIBILITY OF THE ELASTOMER WITH VINYL CHLORIDE, AND (B) A SUSPENSION OR MASS POLYVINYL CHLORIDE OR A CORRESPONDING COPOLYMER, AND A PROCESS FOR THEIR MANUFACTURE. CRYSTAL CLEAR MOULDING COMPOSITIONS OF HIGH IMPACT STRENGTH COMPRISING MIXTURES OF POLYVINYL CHLORIDE WITH GRAFT COPOLYMERS OF VINYL CHLORIDE ON ELASTOMERS AND PROCESS FOR THEIR MANUFACTURE.
