Abstract

This paper reports on an attempt to use CD and CD/PHB ICs as nucleation agents for PHB in a high-speed melt spinning process. At first rheological and thermal properties of the nucleated melts are determined in order to assess the influence of the nucleating agents. Then spinning tests are carried out. Thermal and textile properties of the spun PHB fibers are also determined. An estimation of the improvement of inhibition of the secondary crystallization from use of the described blood compatible nucleating agents is given.

摘要

本文报道了在高速熔体纺丝过程中尝试使用CD和CD/PHB集成电路作为聚羟基丁酸酯（PHB）成核剂的情况。首先测定了成核熔体的流变学和热性能，以评估成核剂的影响。然后进行纺丝试验。还测定了纺制的PHB纤维的热性能和纺织性能。给出了使用所述血液相容性成核剂对二次结晶抑制效果改善情况的估计。
