Abstract Symmetric poly(styrene-b-methyl methacrylate) (PS-b-PMMA, SM) block copolymers were utilized to compatibilize poly(methyl methacrylate) and poly(cyclohexyl methacrylate) (PMMA/PCHMA) melt blends. The effect of molecular weight of SM and PMMA on the morphology of mixed blend and migration of micelle in the mixed phase was characterized by transmission electron microscope (TEM). The results showed that micelles with different morphology were formed when SM was blended with PMMA and PCHMA, respectively. When wet brushes were formed by the block copolymer at the interface of the mixed phase, the micelles generated in PCHMA phase were migrated to PMMA phase. SM improved the compatibility of PCHMA and PMMA, but the degree of compatibility mainly depended on the molecular weight of SM. With the increase of PMMA molecular weight from 19 kg/mol to 39 kg/mol, the average particle size of PMMA increased as well.
