Abstract
The order-order transition temperature (T ooT) in blends of poly(styrene-to-isoprene-b-styrene) (S-l-S) triblock copolymer and polyisoprene (PI) homopolymer was investigated by using synchrotron small-angle X-ray scattering (SAXS). Pure triblock copolymer undergoes an order-order transition (OOT) from hexagonally ordered cylinder (HEX) to body centered cubic (BCC) phases. In order to investigate the effect of the molecular weight of the added homopolymer on T ooT of the triblock copolymer, various low-molecular-weight PI homopolymers were studied. The results revealed that T ooT was affected by the PI molecular weight. T ooT was reduced for blends having low-molecular-weight PI.
