Summary A series of unfractionated and fractionated samples of polyvinyl acetate were prepared by homogeneous solution polymerization of vinyl acetate in N,N-dimethylformamide at 90 °C. in presence of γ, γ-azo-(γ-cyano-n-valeric acid) as initiator under a variety of conditions. A portion of each sample was hydrolysed to polyvinyl alcohol. The number average molecular weights have been determined by end-group titrations. The following molecular weight-intrinsic viscosity relationships for polyvinyl alcohol have been obtained. [η] = 33.88 X 10−5 M 0.716 — for unfractionated samples in water at 30 °C. [η] = 29.51 X 10−5 M 0.716 — for fractionated samples in water at 30 °C.
