SUhlMARYDielectric constants and loss factors have been measured for dilute solutions of methyl poly-methacrylates in toluene and benzene. The molecular weight varied from 14.000 to 1.750.000, the frequencies used ranged from .01 to 35 megacycles, the temperatures from -300 to 25OC.It has been shown that:l o ) The critical frequency and the free energy of activation were 2") The entropy of activation was small and negative. 3 0 ) The static dielectric constant was, for a given concentration,

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.
