Abstract：
 A process for synthesizing polyurethane elastomer containing poly-beta-hydroxybutyrate (PHB) block includes acid-catalytic alcoholyzing PHB to obtain beta-hydroxy butyrate, ester exchange reaction to obtain PHB diol, and reaction on 2,6-ethyl diisocyanate caproate. Its advantages are better biologic compatibility and degradability, and no toxic by-effect of its degradated resultant.
