Refractive indices of monomer‐polymer mixtures of vinyl formate, vinyl acetate, vinyl propionate, and vinyl butyrate

摘要

AbstractMonomers of vinyl formate, vinyl acetate, vinyl propionate, and vinyl butyrate were carefully purified by distillation in a Vigreux column and in a 56‐plate glass helixpacked Todd column. The refractive indices and boiling points of the purified monomers agreed with those given in the literature. The purified samples were exposed to the radiation of a quartz mercury lamp in order to produce several per cent polymer. The refractive indices are tabulated and plotted in graph
