Abstract

Isothermal and nonisothermal crystallization kinetics of poly(phenylene sulfide) (PPS) including a thermotropic liquid crystalline polyesteramide (LCP) have been investigated by means of Avrami and Ozawa expressions. As the LCP content is increased, the supercooling required for PPS crystallization, both half time for crystallization and size of spherulites decrease. Further, the PPS containing LCP exhibits a higher nucleation density than pure PPS when three dimensional growth and constant radial growth rate of spherulites are assumed. In the nonisothermal crystallization process, PPS/LCP blend systems exhibit a notable reduction in Avrami exponent. In the isothermal process, the radius of spherulite linearly increases with time.
