The heat capacity of poly-I-butene, poly-I-pentene, poly-I-hexene, polyisobutylene, poly(4-methyl~I-penten~),polybutadiene,cis-I, 4~poly(2-~~hY!l?utadi~~~112Q!y~y~lQpen iene, poTy(vinyfftuoride), polY(Vlnylidene fiuoride)~--polytrifluoroethylene, polytetrafluoroethylene, poly(vinyl chloride), poly(vinylidene chloride), polychlorotrifluoroethylene, poly(vinyl alcohol), poly(vinyl acetate), poly(a-methylstyrene), poly(o-methylstyrene), poly(o-chlorostyrene) and a series of poly(vinyl benzoate)s is reviewed on the basis of 62 measurements reported in the literature. A set of recommended data has been derived for each polymer. Entropy and enthalpy functions have been calculated for poly-l-hexene, polyisobutylene, cis-I, 4-poly(2-methylbutadiene), poly(vinyl chloride), and poly(a-meth-ylstyrene}. This paper is seventh in a series which will ultimately cover all heat capacity measurements on linear macromolecules..
