摘要：

Two kinds of PCS (PCS-1, PCS-2) with different number average molecular weight and different softening points were synthesized by thermal decomposition and condensation of polydimethylsilane (PDMS). The PCS was melt-spun through a C-shaped spinneret in N2 atmosphere, and then the C-shaped PCS fibers were obtained. The degree of profile of the C-shaped fibers were calculated by means of the cross-section parameters such as outer diameter, inner diameter and stretch angle, which were measured by optical microscopy. The curing degree of the fibers were characterized with the reaction degree of Si-H bond P Si-H which was calculated using infrared spectroscopy.
