POLYESTER RESINS BASED ON TEREPHTHALIC ACID AND 2-METHYL-1,3-PROPANEDIOL AND PROCESSES FOR THE PREPARATION THEREOF

摘要

Unsatured terephthalate-based polyester resins (UPR) based on 2-methyl-1,3-propanediol, a satured 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.
