  • 3-hydroxybutyrate polymer composition
    Patent number: 5061743
    Abstract: Certain hydroxy alkanoate polymers, such as 3-hydroxybutyrate polymers, when obtained by solvent extraction from fermentation masses, can have long cycle times during thermal processing due to a low rate of crystallization. A combination of (a) an organophosphonic or organophosphoric acid or ester with (b) an oxide, hydroxide, or carboxylate of a metal of Groups I to V is an effective nucleating agent.
