PLASTICIZERS CONSISTING OF HIGH MOLECULAR WEIGHT POLYESTERS, CHAIN EXTENSION COMPATIBLE WITH VINYL HALOGENIDE POLYMERS |
abstract |
Plasticizers made from high molecular weight polyesters. Plasticizers are saturated, linear, solid, chain-extending polyesters having a number average molecular weight of at least 40,000 and having a methylene group / carbonyloxy group ratio of from about 4: 1 to about 7: 1; these chain-extending polyesters, having the characteristics given above, are prepared by reacting a polyester prepolymer with a chain-extending agent. The present invention is particularly useful for providing chain-extended polyesters used as plasticizers for vinyl halide polymers. |
