Abstract

Poly((R)-3-hydroxyalkanoate)s (PHAs) are bacterial storage polyesters, currently receiving much attention because of their potential application as biodegradable and biocompatible plastics. Among them are the PHAs from Pseudomonas oleovorans, which are semicryst. elastomers. Their applicability is seriously limited by their low melting temp. as well as by their low crystn. rate. Both problems were overcome by crosslinking of unsatd. pendent groups, which were incorporated in the polymer by tailoring the carbon source for biosynthesis. Crosslinking was established by electron-beam irradn. and resulted in a true rubber with const. properties over a large temp. range from -20 to +170 DegC. Even after crosslinking, the material was still biodegradable. To the authors' knowledge this is the first microbially produced biodegradable rubber
