Abstract:This article describes the synthesis and characterization of semicrystalline copolymer based on dihydroxy-terminated polystyrene and a uniform crystallizable diamide (T T or T6T) hard segment. The concentration of the diamide in the copolymer varies from 3 to 15 wt% by changing the length of soft segments using dimethylterephthalate as a chain extender. The inherent viscosity of the polymer is very high ranging between 1.6 and 2.9 dL/g. Differential scanning calorimetry spectrum shows T g for soft and T m for … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
