【摘要】 <正>通过在尼龙6中添加无机填料无水氯化钙进行改性,可以降低尼龙6的加工温度制备低熔点尼龙6(LPA6)。LPA6保持尼龙6优良阻隔性能、耐化学药品性能及自润滑性,但与尼龙6相比,存在冲击强度低,耐热性能及流变性差等缺点。液晶聚合物(LCP)具有优异更多还原

【Abstract】 Hybrid composite systems consisting of low melting point polyamide 6(LMPA6) and liquid crystalline polymer(LCP) was prepared.When LCP phr above 5 through to fibrillation of LCP proved by SEMs the flexural strength and flexural modulus increased in blends.The additions of LCP influence the crystallization of LPA6,a small amount of LCP can increase the crystal temperature and crystalline of LPA6 while the LCP phr was 20 the crystal temperature and crystalline decreased.As the addition of LCP also increased the Vicat softening point of blends with the increase of LCP content the Vicat softening point was decreased in relief which was correspondence with DSC.更多还原
