Sequestered amorphous polyhydroxyalkanoate polymer (SAPP) material derived from cellular biomass and production thereof

摘要

The present invention provides an efficient and cost-effective process to recover highly purified PHA homopolymers and copolymers, producing novel sequestered amorphous polyhydroxyalkanoate polymer (SAPP) materials derived from cellular biomass that are crystal competent. Such resulting materials (e.g., melt-derived solids and crystalline agglomerates), as well as methods of production of the sequestered amorphous polyhydroxyalkanoate polymer (SAPP) materials and subsequent processing, demonstrate cost-effective production of PHA polymer at commercial scale, which is heretofore not been achievable. Moreover, the methods and materials produced make feasible the long-awaited achievement in the industry for competitive commercialization of PHA homopolymers and copolymers from cellular biomass.
