Polyester plasticizer for polyvinyl chloride fabrics

Abstract

Abstract THE INVENTION RELATES PRIMARILY TO DRYCLEANABLE VINYL FABRICS AND OTHER VINYL CONSTRUCTIONS AND TO NOVEL PLASTICIZERS FOR POLYVINYL CHLORIDE RESINS HAVING AN IMPROVED RESISTANCE TO EXTRACTION IN DRYCLEANING SOLVENTS, SUCH AS PERCHLOROETHYLENE. MORE PARTICULARLY, THE INVENTION RELATES TO NEW POLYMERIC PLASTICIZERS AND POLYVINYL CHLORIDE RESINS PLASTICIZED THEREWITH. THE PLASTICIZERS COMPRISE NON-CHAIN TERMINATED POLYESTERS HAVING A MOLECULAR WEIGHT RANGE OF FROM ABOUT 1500 TO 30,000 RESULTING FROM ESTERIFICATION OF A DIBASIC ACID-GLYCOL REACTION MIXUTRE CONSISTING ESSENTIALLY OF TWO OR MORE ALKANEDIOIC ACIDS HAVING FROM 4 TO 12 CARBON ATOMS, AND TWO OR MORE DIFFERENT ALKYLENE GLYCOLS HAVING FROM 2 TO 6 CARBON ATOMS, AT LEAST ONE HAVING 2 OR 3 CARBON ATOMS AND AT LEAST ONE HAVING 3 TO 6 CARBON ATOMS IN WHICH THE CONTENT OF DIBASIC ACIDS BELOW C6 IS FROM ABOUT 0-50 EQUIVALENT PERCENT, THE CONTENT OF C6 TO C9 DIBASIC ACIDS IS FROM ABOUT 50-100 EQUIVALENT PERCENT, AND THAT OF C19 TO C12 DIBASIC ACIDS IS FROM 0-50 EQUIVALENT PERCENT, BASED ON THE TOTAL EQUIVALENTS OS DIBASIC ACID, AND THE CONTENT OF C2 TO C3 AND C3 TO C6 GLYCOLS EACH BEING FROM 20-80 EQUIVALENT PERCENT BASED ON THE TOTAL EQUIVALENTS OF GLYCOL IN THE REACTION MIXTURE. THE PLASTICIZERS OF THIS INVENTION MAY ALSO INCLUDE FROM 1 TO ABOUT 40% BY WEIGHT BASED ON THE WEIGHT OF THE POLYESER OF A SUPER POLYESTER POLYMER HAVING A MOLECULAR WEIGHT OF ABOVE 15,000.
