Abstract

The development of poly(ϵ-caprolactone) (PCL) crystallinity in poly(ϵ-caprolactone)/poly(styrene-co-acrylonitrile) blends of 20% by weight PCL was studied for samples prepared under a variety of conditions. Solution casting was observed to be a method capable of inducing considerable PCL crystallinity, whereas melt blending yielded amorphous samples. The degree of crystallinity of samples prepared from blend solutions was found to be sensitive to a variety of factors. Film thickness, blend preparation temperature, solvent evaporation rate, and the blending solvent were all shown to affect the development of PCL crystallinity. Solvent retention time during film formation was postulated to be responsible for the observed behavior.
