THERMALLY STABLE BIOPOLYESTER

摘要

PROBLEM TO BE SOLVED: To provide a biopolyester having improved heat stability. SOLUTION: The biopolyester obtained by substituting a hydroxy group at the terminal of a molecular chain with a carboxylic ester group is produced by reacting a carboxylic acid with a biopolyester which is a poly(3-hydroxyalkanoate) or a copolymer of the poly(3-hydroxyalkanoate).
