The molar mass distributions of various polyvinylalcohol (PVA) samples having molar masses ranging from 14 to 610 kg mol - 1 have been determined by size exclusion chromatography (s.e.c.) using dimethylsulfoxide (DMSO) as the eluent. Four sets of columns were tested. The best results were ...

Polyvinyl alcohol was condensed with straight and branched chain aldehydes (C n H 2 n O, n = 2 to 8) to varying degrees of completion. Measurements on resins and plasticized compositions included apparent modulus of elasticity at variou... AF Fitzhugh,RN Crozier - 《Journal of Polymer Scienc...
The estimated value for K8 seems reasonable and is somewhat lower than the only value reported in the literature, which is claimed to have been obtained under theta-conditions, namely K8 = 0.156 in benzyl alcohol at 155.4°C by Sato et al. 41 The calculated value for B, however, is ...
