Abstract
The blends of poly(trimethylene terephthalate) (PTT) with maleated styrene-butylene-co-ethylene-styrene copolymer (SEBS-g-MA) were prepared by melt blending. Their morphologies and crystallization behavior were investigated. Morphology observation shows the well-dispersed phase of SEBS-g-MA in PTT matrix and the partical size of SEBS-g-MA increased as the content of SEBS-g-MA increasing. Differential scanning colorimetry(DSC) experiments showed that the melting point of pure PTT and their blends was almost constant. Addition of 5-30wt% SEBS-g-MA in blends increased crystallization points of PTT phase and the crystallinity of the blends were higher than that of PTT.
