Abstract:
A polyhydroxyalkanoate copolymer comprises one kind of unit of —[OCH((CH2)x—SOC6H5R)CH2CO]— (n=1-7) (1) (wherein R is any one of H, halogen, CN, NO2, COOR′, SO2R″ (R′ is any one of H, Na, K, CH3 and C2H5; R″ is any one of OH, ONa, OK, halogen, OCH3 and OC2H5), CH3, C2H5, C3H7, (CH3)2—CH and (CH3)3—C) and —[OCH((CH2)x—SO2C6H5R)CH2CO]— (n=1-7) (2) (wherein R is any one of H, halogen, CN, NO2, COO R′, SO2R″ (R′ is any one of H, Na, K, CH3 and C2H5; R″ is any one of OH, ONa, OK, halogen, OCH3 and OC2H5), CH3, C2H5, C3H7, (CH3)2—CH and (CH3)3—C) and at least one unit of chemical formulae (3) to (6): —[OCH((CH2)m—Rz)CH2CO]— (n=1-8) (3) (wherein Rz comprises a residue having either a phenyl structure or a thienyl structure), —[OCH((CH2)k—C6H11Ra)CH2CO]— (n=1-8) (4) (wherein Ra is any one of H, CN, NO2, halogen, CH3, C2H5, C3H7, CF3, C2F5 and C3F7) —[OCH((CH2)n—CH═CH2)CH2CO]— (n=1-8), and (5) —[OCH((CH2)n—COORb)CH2CO]— (n=1-8) (6) (wherein Rb is any one of H, Na and K).
