Abstract

The structure and thermal behavior of new types of bacterial copolyesters, poly(3-hydroxybutyrate) (PHB) and related bacterial poly(hydroxyalkanoates) (PHA), are investigated. PHAs are completely biodgradable under both aerobic and anaerobic conditions and can be produced from renewable resources. Among all natural polymers, only PHA polymers show thermoplasticity and mechanical properties similar to those of synthetic polymers. PHB, which is one of the simplest and largely produced bacterial polyesters in the PHA family, possess similar glass transition temperature, melting point, and comparable ultimate tensile strength to those of isotactic polypropylene.
