摘　　要：在 PVAC-CH_3OH 溶液中加入 SiO_2进行干法纺丝。研究了 PVAC-SiO_2纤维的结构与性能。实验结果表明,SiO_2能够提高 PVAC 纤维的强度、模量和热稳定性。The PVAC-SiO_2 dispersion system was spun into fiber by dry-spinning, The SiO_2 effects on the mechanical property/morphology,viscoelasticity and the thermal behavoir of PVAC-SiO_2 fiber were discussed.The effects were based according to the mschanics,the method of the velocity of sound,the X-diffractlon of wide angle,the bircefraction,electron microscope,viscoelastc spectrum and the thermal behavoir,Both the tenacity,and thermal resistance of PVAC-SiO_2 fiber were improved,as well as The PVAC-SiO_2 fiber itself.
