Abstract
Abstract The nature of polymethacrylate (PMA) interactions with n-octacosane (n-C28) was probed using differential scanning calorimetry and powder X-ray diffraction. Blends containing comblike homopolymer and copolymer methacrylates were chosen to investigate the role of polymer side-chain crystallinity upon the crystallization behavior of n-C as a model n-paraffin compound. All PMAs disrupted the platelet morphology of the n-C28 while enhancing development of crystal planes along the n-paraffin chain axis. In addition, evidence supporting both orthorhombic phase stabilization and cocrystallization is reported for one solidified melt containing poly(n-octadecyl methacrylate).
