synopsisThe effect of the extent of degradation of poly(p-N,Ndimethylaminostyrene) on the quantity and composition of the residue and the effect of pyrolysis temperature on the fraction volatile a t pyrolysis temperature are discussed. The behavior of poly(p-N,Ndimethylaminostyrene) is compared to that of polystyrene. A significant difference has been found for the behavior of the residue from poly(p-N,N-dimethylaminostyrene), which is ascribed to a crosslinking reaotion involving the dimethylamino substituent .Mechanisms to account for the observed products of degradation have been suggested and are discussed.
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.
