Elastic Polyesters from Glycerol and Azelaic Acid

Abstract:

Article Preview

Elastic polyester from glycerol and azelaic acid with different molar ratio was synthesized by simple catalyst-free esterification reaction. The ratio of azelaic acid to glycerol used in this experiment was 1:2, 1:1 and 2:1. The polyester with ratio 1:2 and 1:1 appear as clear, bubble free, non tacky and flexible after 48 hours at 125°C while the polyester with the ratio of 2:1 was cured after extension of 60 hours. The formation of ester bonds of the polyester produced is detected on the monomer molecular ratio and also on the efficiency of water removal during esterification process.
