| Abstract: | PVC was modified by low melting PA6（LPA6）/ liquid crystal polymer composites, and influences of LPA6/LCP content on the mechanical properties and Vicat softening points of PVC/LPA6/LCP blends were studied. The results showed that the addition of LPA6/LCP could significantly enhance the flexural strength and flexural modulus of the blends when the content of LPA6/LCP was less than 10%, and when the content of LPA6/LCP was less than 30%, the addition of LPA6/LCP could obviously promote the Vicat softening point of the blends. |
| Keywords: | PVC low melting PA6 liquid crystal polymer mechanical property |
