Confined crystallization behavior of pofy(ε-caprolactone) was studied by DSC

WAXD and SAXS in the mixtures of poly(ε-caprolactone)(PCL) and poly(styrene-co-aceonitfile)(SAN) Because the crystallization and melting temperatures of PCL ale lower than the slass transition temperature of SAN

the experimental results indicated that multi-scale crystallization behavior of PCL is confifled in the mixtures．DSC measurements showed that the erystallinity 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.
