Vinylidene chloride polymer compositions
Abstract
Abstract THIS INVENTION IS DIRECTED TO IMPROVEDPOLYMERIC COMPOSITIONS COMPRISING IN INTIMATE BLENDED COMBINATION: (1) FROM ABOUT 88 TO 99.5 PERCENT BY WEIGHT , BASED ON THE TOTAL WEIGHT OF THE COMPOSITION, OF A NORMALLY CRYSTALLINE VINYLIDENE CHLORIDE POLYMER CONTAINING FROM ABOUT 70 TO ABOUT 95 PERCENT BY WEIGHT OF VINYLIDENE CHLORIDE, (2) FROM ABOUT 0.25 TO 6 PERCENT BY WEIGHT OF AN ETHYLENE POLYMER OF (A) FROM ABOUT 100 TO 58 PERCENT BY WEIGHT ETHYLENE AND (B) BETWEEN ABOUT 0 TO 42 PERCENT BY WEIGHT OF VINYL ACETATE, AND (3) FROM ABOUT 0.25 TO ABOUT 6 PERCENT BY WEIGHT OF A SECOND INTERPOLYMER OF FROM ABOUT 0 TO 91 PERCENT BY WEIGHT OF VINYL CHLORIDE AND FROM ABOUT 100 TO 9 PERCENT BY WEIGHT OF VINYL ACETATE. THESE COMPOSITIONS PROVIDE SHAPED ARTICLES HAVING UNEXPECTEDLY ENHANCED RESISTANCE TO TEAR.
