牌号简介 |
PHB及其与聚羟基戊酸盐(PHV)的共聚物是由可再生碳水化合物原料经生物发酵制成的可熔融加工半结晶热塑性塑料。它们被描述为“生物技术中真正的热塑性塑料的第一个例子”,也可以生物降解。虽然在日常条件下相当稳定,但它们在体内和堆肥或填埋场降解缓慢。[乙肝单体单位是人体血液的正常组成部分]由于受到酸和碱的侵蚀并溶解在氯化溶剂中,因此它们的耐化学性受到一定限制。更值得注意的是,它们是光学活性聚合物,在每个分子重复单元中都有手性位点,所有这些都处于D(或R)构型。PHB均聚物是一种高结晶度的硬脆聚合物,其力学性能与聚苯乙烯相同,但其脆性较低,耐温性较高。因此,共聚物是通用的首选。人们认为,最有可能应用均聚物的领域是医学/生物领域。耐化学性:酸-稀释的公平醇-公平碱-劣质润滑脂和油-良好的抗紫外线-公平 PHB and its copolymers with polyhydroxyvalerate (PHV) are melt-processable semi-crystalline thermoplastics made by biological fermentation from renewable carbohydrate feedstocks. They have been described as "the first example of a true thermoplastic from biotechnology" and are also biodegradeable. Although quite stable under everyday conditions they degrade slowly in the body and when composted or in landfill sites. [The HB monomer unit is a normal constituent of human blood.] Their chemical resistance is somewhat limited as they are attacked by acids and alkalis and dissolve in chlorinated solvents. Rather remarkably, they are optically active polymers with a chiral site in each molecular repeat unit, all of which are in the D- (or R) configuration. PHB homopolymer is a stiff and rather brittle polymer of high crystallinity, whose mechanical properties are not unlike those of polystyrene, though it is less brittle and more temperature resistant. Hence, copolymers are preferred for general purposes. It is believed that the most likely area for the application of homopolymer is in the medical/biological fields.
