Abstract
A fluorescence technique is used to determine critical micelle concentrations (CMCs) of styrene-containing block and gradient copolymers dispersed within a homopolymer. Block copolymer composition and molecular weight are varied to determine what factors impact the CMC. Gradient copolymers are shown to have higher CMCs than block copolymers due to the gradient in comonomer composition along the copolymer backbone. Gradient copolymers can be more effective as compatibilizing agents, as they are less likely to be trapped within micelles upon melt processing.
