Vinyl resins plasticized with polycarbonate polymers

Claim 2

A VINYL RESIN PLASTICIZED COMPOSITION COMPRISING A VINYL RESIN AND, AS THE PLASTICIZER THEREFOR, A POLYCARBONATE HAVING AN AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 300 TO ABOUT 9000 AND CHARACTERIZED BY THE FORMULA

Claim 3

A VINYL RESIN PLASTICIZED COMPOSITION COMPRISING A VINYL RESIN AND, AS THE PLASTICIZER THEREFOR, A POLYCARBONATE WHICH IS CHARACTERIZED BY AT LEAST ONE CARBONYLOXYALKYLENEOXY UNIT THEREIN, SAID UNIT HAVING A TERMINAL CARBONYL GROUP AT ONE END, AN OXY GROUP AT THE OTHER END, AND AN INTERMEDIATE OXYALKYLENE CHAIN OF ONE OXYGEN ATOM AND THREE CARBON ATOMS, SAID OXYGEN ATOM BEING BONDED TO THE TERMINAL CARBONYL GROUP OF SAID CARBONYLOXYALKYLENEOXY UNIT; SAID POLYCARBONATE BEING FORMED VIA THE REACTION COMPRISING (1) CONTACTING AN ADMIXTURE CONTAINING A SUBSTITUTED 2,6-DIOXACYLOHEXANONE, WITH AN INITIATOR OF THE GROUP CONSISTING OF GLYCOLS, DIAMINES, AND AMINO ALCOHOLS, SAID ADMIXTURE BEING IN MOLAR EXCESS WITH RELATION TO SAID INITIATOR, AT A TEMPERATURE OF AT LEAST ABOUT 50*C., FOR A PERIOD OF TIME TO PRODUCE A HYDROXYL TERMINATED POLYCARBONATE PRODUCT; (2) THEREAFTER CONTACTING SAID POLYCARBONATE PRODUCT WITH A MOLECULAR DEFICIENCY OF A DICARBOXYLIC ACID, AT AN ELEVATED TEMPERATURE, TO THUS PRODUCE A CHAIN EXTENDED HYDROXYL TERMINATED POLYCARBONATE PRODUCT; AND (3) SUBSEQUENTLY ACYLATING THE TERMINAL HYDROXYL GROUPS THEREOF WITH A COMPOUND OF THE GROUP CONSISTING OF ANHYDRIDES AND ORGANIC ACIDS WHICH CONTAIN A SOLE CARBOXYL GROUP.

Claim 4

A VINYL RESIN PLASTICIZED COMPOSITION COMPRISING A VINYL RESIN AND, AS THE PLASTICIZER THEREFOR, A POLYCARBONATE WHICH IS CHARACTERIZED BY AT LEAST ONE CARBONYLOXYALKYLENEOXY UNIT THEREIN, SAID UNIT HAVING A TERMINAL CARBONYL GROUP AT ONE END, AN OXY GROUP AT THE OTHER END, AND AN INTERMEDIATE OXYALKYLENE CHAIN OF ONE OXYGEN ATOM AND THREE CARBON ATOMS, SAID OXYGEN ATOM BEING BONDED TO THE TERMINAL CARBONYL GROUP OF SAID CARBONYLOXYALKYLENEOXY UNIT; SAID POLYCARBONATE BEING FORMED VIA THE REACTION COMPRISING (1) CONTACTING AN ADMIXTURE CONTAINING A SUBSTITUTED 2,6-DIOXACYLOHEXANONE, WITH AN INITIATOR OF THE GROUP CONSISTING OF GLYCOLS, DIAMINES, AND AMINO ALCOHOLS, SAID ADMIXTURE BEING IN MOLAR EXCESS WITH RELATION TO SAID INITIATOR, AT A TEMPERATURE OF AT LEAST ABOUT 50*C., FOR A PERIOD OF TIME TO PRODUCE A HYDROXYL TERMINATED POLYCARBONATE PRODUCT; (2) THEREAFTER CONTACTING SAID POLYCARBONATE PRODUCT WITH A MOLECULAR DEFICIENCY OF A DICARBOXYLIC ACID, AT AN ELEVATED TEMPERATURE, TO THUS PRODUCE A CHAIN EXTENDED HYDROXYL TERMINATED POLYCARBONATE PRODUCT; AND (3) SUBSEQUENTLY ACYLATING THE TERMINAL HYDROXYL GROUPS THEREOF WITH A COMPOUND OF THE GROUP CONSISTING OF ANHYDRIDES AND ORGANIC ACIDS WHICH CONTAIN A SOLE CARBOXYL GROUP.
