Abstract
The invention provides a polyhydroxyalkanoate having a bromo group in a unit and being thermally stable and capable of arbitrarily controlling physical properties, and a producing method thereof. According to the invention, there are provided a polyhydroxyalkanoate copolymer including a 3-hydroxy-ω-bromoalkanoic acid unit represented by a formula—[OCH((CH)Br)CHC(O)]— (n=1 to 8) (1) and a unit represented by a formula —[OCH((CH)R)CHC(O)]— (2) within a same molecule, and a method for producing a polyhydroxyalkanoate copolymer by microorganisms, utilizing a ω-bromoalkanoic acid represented by a formula Br(CH)CHCHCOOH (p=1 to 8) (20) and a compound represented by a formula R(CH)CHCHCOOH (21) as raw materials.
