在PHB的均聚物是一种高结晶度，其不同于那些不聚苯乙烯力学性能，比较脆硬聚合物，虽然它是那么脆弱。
The 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.
丙烯酸改性与乳化同时进行时，其聚合物链结构中软、硬段分布均匀；
Soft and hard segments in polymer chains were well-distributed when acrylate modification and emulsification performed at the same time.
随着盐浓度进一步增加，聚合物-离子相互作用增强，体系中硬段结构出现新的聚集形态。
With further increase of salt concentration, interaction between polymer and ion enhanced, which brought about the formation of new hard - segment aggregates.
