For this study, polystyrene (PS) and poly(2-hydroxyethyl methacrylate) (PHEMA) were used as a pair of immiscible homopolymers, and polystyrene-block-poly(2-vinylpyridine) (S2VP diblock) copolymer was used as a functionalized compatibilizer. The rationale behind the choice of the ternary blend system lies in that the hydroxyl groups in PHEMA and the pyridine groups in the poly(2-vinylpyridine) (P2VP) block of S2VP diblock copolymer are expected to form hydrogen bonds, enhancing the miscibility between the PS and the PHEMA in the ternary blends. Indeed, the presence of specific interactions (hydrogen bonding) between PHEMA and S2VP diblock copolymer was observed via Fourier transform infrared spectroscopy, inducing a diffuse interphase between PS and PHEMA in the ternary blend during melt blending above the order-disorder transition temperature of the diblock copolymer. However, the interphase was not thermally stable. The diblock copolymer in the interphase was driven into the PHEMA-rich phase due to the specific interactions. Micelles of the diblock copolymer formed when its local concentration exceed the critical micelle concentration threshold. 2006 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1165330955 http://rave.ohiolink.edu/etdc/view?acc_num=akron1165330955 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
