Title:
側鎖にブロモ基を有するユニットを分子中に含む新規なポリヒドロキシアルカノエート共重合体及びその製造方法
Document Type and Number:
Japanese Patent JP3754956
Kind Code:
B2
Abstract:
The invention provides 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- omega -bromoalkanoic acid unit represented by a formula -ÄOCH((CH2)nBr)CH2C(O)Ü- (n=1 to 8) (1) and a unit represented by a formula - ÄOCH((CH2)mR)CH2C(O)Ü- (2) within a same molecule, and a method for producing a polyhydroxyalkanoate copolymer by microorganisms, utilizing a omega -bromoalkanoic acid represented by a formula Br(CH2)pCH2CH2COOH (p=1 to 8) (20) and a compound represented by a formula R(CH2)qCH2CH2COOH (21) as raw materials. (In the formulae, R designates a residue selected from the group consisting of a phenyl structure, a thienyl structure and a cyclohexyl structure. m and q are integers selected from 1 to 8 respectively, provided it may be 0 when R designates the cyclohexyl structure. n and p designate integers within the ranges in the formulae respectively. These respective residues and integers in one unit are independent of respective one in another unit.)
