Abstract
It is shown that heating for several days at atmospheric pressure and 100°C. does not remove the volatile components from benzene solutions of polymethylmethacrylate and polystyrene solutions in benzene. Pirani gage measurements in a molecular still define the rather limited conditions under which all volatile components can be removed with out degradation and loss of polymer. Because of its low softening point, polyvinyl acetate can be dried to constant weight by overnight heating at 100°C.Keywords
