Abstract
Improved chain-stopped polyester plasticizers for polyvinyl chloride homopolymers and copolymers are provided. The plasticizers show little or no tendency to migrate from PVC, yet they are readily processable with the PVC. While being extremely compatible with PVC the present plasticizers have very low affinity for ABS and polystyrene resins and therefore can be used in applications where plasticized PVC comes in contact with these other resins.
