Abstract: THE PRESENT INVENTION RELATES TO CRYSTAL CLEAR GRAFT COPOLYMERS OF HIGH IMPACT STRENGHT AND THEIR MANUFACTURE BY POLYMERIZING VINYL CHLORIDE TO AN EXTENT OF POLYMERIZATION OF 50 TO 85%, THEN ADDING AN ELASTOMER LATEX OBTAINED FROM BUTADIENE, STYRENE AND VINYL ESTERS, IN AN AMOUNT WITHIN THE RANGE OF FROM 1 TO 30% BY WEIGHT CALCULATED ON THE VINYL CHORIDE AND FINALLY CONTINUING THE POLYMERIZATION OF THE WHOLE MIXTURE. THE RESULTING GRAFT COPOLYMERS CAN BE USED EITHER ALONE OR IN ADMIXTURE WITH SUSPENSION OR MASS POLYVINYL CHLORIDE FOR MAKING CRYSTAL CLEAR SHAPED ARTICLES OF HIGH NOTCHED IMPACT TENSILE STRENGTH.
