Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
A COMPOSITION OF MATTER COMPRISING A UNIFORM ADMIXTURE OF A VINYL CHLORIDE POLYMER CONTAINING AT LEAST 80 WEIGHT PERCENT POLYMERIZED VINYL CHLORIDE WITH FROM 0.5 TO 50 WEIGHT PERCENT, BASED ON THE WEIGHT OF SAID VINYL CHLORIDE POLYMER, OF A GRAFT POLYMER CONSISTING OF A COPOLYMER OF BUTADIENE AND AN ALKYL ACRYLATE WHOSE HOMOPOLYMER HAS A HEAT DISTORTION TEMPERATURE OF LESS THAN 0*C., SAID COPOLYMER CONTAINING FROM 1 TO 20 WEIGHT PERCENT POLYMERIZED BUTADIENE, THE BALANCE BEING POLYMERIZED ALKYL ACRYLATE, AND FROM 10 TO 185 WEIGHT PERCENT BASED ON THE WEIGHT OF SAID COPOLYMER, OF METHYL METHACRYLATE GRAFTED ONTO SAID COPOLYMER.
Claim 2
Dependent Claim
