Branched structures are formed in the main chain of aliphatic polyesters such as aliphatic dihydric carboxylic acids such as succinic acid and adipic acid, ethylene glycol, 1,4-butanediol, and 1,2-butanediol and 1,3-butanediol. Biodegradable aliphatic polyesters prepared by mixing esterified aliphatic dihydric alcohols, adding titanate-based catalysts, and carrying out condensation polymerization reactions under high temperature and high vacuum have excellent properties and processability. It can be effectively applied to blending products. |
