Abstract

The compatibility and crystallization behavior of poly(phenyl acetylene) (PPA)/polycaprolactone (PCL) blends were investigated. PPA and PCL were partially miscible in the melt. PCL composition in the PCL-rich phase was calculated from the observed glass transition temperature with the consideration of the perturbation of amorphous phase composition by the crystallization of PCL. PCL composition in PCL-rich phase ranged from ca. 91 wt% to 94 wt%. The melting point of PCL was depressed upon blending. The isothermal crystallization kinetics of the blends was analyzed by Avrami equation. The crystallization rate decreased with increasing PPA composition in the PCL-rich phase. The crystal fold surface free energy σ_e of ca. 90 erg cm^-2 was obtained from Lauritzen-Hoffman analysis considering regime II kinetics. Fold surface free energy was found to increase slightly with PPA composition.
