Abstract
Unsaturated terephthalate-based polyester resins (UPR) based on 2-methyl-1,3-propanediol, a saturated dicarboxylic acid or derivative thereof, and an unsaturated dicarboxylic acid or derivative thereof be prepared without use of a catalyst in reasonable cycle times. UPR based on these monomers exhibit exceptional solubility in styrene, and are thus useful in polyester molding resins.
