Abstract
Hydroxyterminated PHA is produced by cultivating a PHA-producing microorganism in the presence of an aliphatic diol or an aliphatic polyol. High molecular weight hydroxy-terminated PHA is obtainable by the disclosed process, and is useful in the production of graft, block and random polymers and copolymers with other monomers, oligomers and polymers containing appropriate functionality and end group compatibility.
Claims5
A random or random block polymer or copolymer composition comprising the reaction product of hydroxy-terminated PHA and a different polyester, copolyester, polyamide or organic dicarboxylic, acid wherein the molecular weight of the hydroxy-terminated PHA is greater than about 3000.
