Abstract
The purpose of the present invention is to provide a PHA, in particular PHBV, having a molecular weight exceeding 3,610,000 and/or a method for producing such a PHA while controlling the molecular weight thereof. Provided is a copolymer of random copolymerization of 3-hydroxybutanoic acid and 3-hydroxyvaleric acid, having a weight-average molecular weight exceeding 3,610,000.
