Vinyl halide resins plasticized with an alkanol terminated oligoester

Claim 1

A PLASTICIZED VINYL CHLORIDE RESINOUS COMPOSITION COMPRISING A VINYL CHLORIDE RESIN SELECTED FROM THE GROUP CONSISTINF OF HOMOPOLYMERS OF VINYL CHLORIDE AND COPOLYMERS OF VINYL CHLRIDE WITH AN ETHYLENICALLY UNSATURATED MONOMER, SAID COPOLYMER CONTAINING AT LEAST ABOUT 60% BY WEIGHT OF COMBINED VINYL CHLORIDE, AND INCORPORATED THEREIN A PLASTICIZING AMOUNT OF AN ALKANOL TERMINATED OLIGOESTER HAVING THE GENERAL FORMULA R-(A-G)X-A-R WHEREIN R IS A SATURATED ALIPHATIC ALCOHOL RESIDUE CONSISTING OF A HYDROCARBON NUCLEUS AND AN OXYGEN ATOM LINKED THERETO HAVING AN AVERAGE CARBON CONTENT OF 7 TO 13 CARBON ATOMS, A IS AN ORGANIC DIBASIC ACID RESIDUE CONSISTING OF A HYDROCARBON NUCLEUS AND TWO CARBONYL GROUPS LINKED THERETO, SAID ORGANIC DIBASIC ACID RESIDUE FURTHER HAVING AN AVERAGE OF 4 TO 14 CARBON ATOMS DERIVED FROM A MIXTURE OF AN ALIPHATIC DIBASIC ACID AND AN AROMATIC DIBASIC ACID, G IS A GLYCOL RESIDUE CONSISTING OF A HYDROCARBON NUCLEUS AND TWO OXYGEN ATOMS LINKED THERETO HAVING AN AVERAGE OF 2 TO 66 CARBON ATOMS, X REPRESENTS THE NUMBER OF RECURRING GLYCOL DIBASIC ACID UNITS IN THE OLIGOESTER AND RANGES FROM 1.2 TO 4.6, THE OLIGOESTER BEING FURTHER CHARACTERIZED BY THE FACT THAT THE VALUE FOR Y, THE MOLAR PERCENT OF THE AROMATIC RESIDUE IN THE ORGAIC ACID RESIDUE OF THE OLIGOESTER AND THE VALUE FOR X IS A COMMON POINT FALLING WITHIN THE PENTAGRAM ABCED OF FIGURE I OF THE ANNEXED DRAWING, AND THAT THE VALUE FOR N, THE SUM OF THE CARBON ATOMS IN ONE MOLE OF THE COMPONENTS R, A, AND G OF THE OLIGOESTER IS NOT LESS THAN THE VALUE REPRESENTED BY A LINE BELONGING TO A FAMILY OF LINES, THE LIMITS OF WHICH ARE AB AND DC.
