CRYSTAL STRUCTURE AND THERMAL BEHAVIOR OF THREE DIFFERENT TYPES OF PHB COPOLYMERS BY USING INFRARED SPECTROSCOPY AND X-RAY DIFFRACTION
Poly(3-hydroxybutyrate) (PHB) has recently been a matter of great interest because it has similar thermal and mechanical properties to isotactic polypropylene (iPP). However the high crystallinity of PHB makes it rigid and stiff, not necessarily well-suited for certain applications as a commodity plastic. To reduce the excess crystallinity and modify the overall physical properties of PHB, other monomers are sometimes copolymerized with PHB. The purpose of the present study is to compare thermal behavior among P(HB-co-3HHx) with middle long-sidechain, P(HB-co-HO) with 3-hydroxyoctanoate with longer side-chain, and P(HB-co-6HHx) with 6hydroxyhexanoate with no side-chain (Fig. 1) by means of infrared spectroscopy (IR) and wide-angle X-ray diffraction (WAXD).
