A novel polyhydroxyalkanoate having a monomer unit represented by the formula (1), the unit having a carboxyl group substituting a ring structure at the end of side chain, obtainable by oxydizing vinyl or methyl group substituting a ring structure at the end of the side chain. The polyhydroxyalkanoate has high thermal stability, charge stablity, a high charge amount, improved dispersibility and biodegradability together, and therefore, suitable for resin moldings, and binders and charge controlling agents for toners used in the electrophotographic process.
一种新型聚羟基烷酸酯,其单体单元由式(1)表示,单元侧链末端有一个羧基取代的环状结构,可通过将取代侧链末端环状结构的乙烯基或甲基氧化而获得。这种聚羟基烷酸酯具有较高的热稳定性、电荷稳定性、较高的电荷量、较好的分散性和生物降解性,因此适用于树脂成型、电子照相工艺中墨粉的粘合剂和电荷控制剂。
