LIQUID COPOLYESTER PLASTICIZERS DERIVED FROM 1,4-BUTANEDIOL AND A DICARBOXYLIC ACID MIXTURE |
摘要 |
Liquid copolyesters useful as plasticizers for vinyl resins are provided. The copolyesters are obtained by the esterification of specific aliphatic dicarboxylic acid ester mixtures with 1,4-butanediol and an aliphatic saturated monofunctional alcohol. The copolyesters have acceptably low solidification points; they are resistant to hydrocarbon extraction; and they impart good low-temperature flexibility to PVC compositions plasticized therewith. |
