Unlike PHA modification via manipulation of the fermentation process, chemical reactions allow for the bulk production of a uniform product and incorporation of diverse functional groups to produce useful tailor-made polymers with desirable properties for niche applications. PHA modification by chemical processes can be achieved by different methods such as car-bojq lation, hydrojylation, epoxidation, chlorination, grafting reaction etc. (Figure 7.1). ...
