摘要：

Confined crystallization behavior of poly(epsilon-caprolactone) was studied by DSC,WAXD and SAXS in the mixtures of poly(epsilon-caprolactone) (PCL) and poly(styrene-co-acrylonitrile) (SAN). Because the crystallization and melting temperatures of PCL are lower than the glass transition temperature of SAN, the experimental results indicated that multi-scale crystallization behavior of PCL is confided in the mixtures. DSC measurements showed that the crystallinity of PCL is reduced with increasing the SAN concentration in mixtures. WAXD and SAXS results indicated that both PCL crystallite size and lamellae structure are disturbed by SAN with high glass transition temperature in the mixtures.
