The factors which influence the drying of liquid vinyl monomers with molecular sieves are discussed. It is found that the best results are obtained by drying the monomer for at least 12 hr at −15°C on molecular sieves that received no pretreatment at elevated temperatures. Although the prepolymerization that takes place on the molecular sieves during the drying can be quite extensive, the excellent reproducibility that can be achieved by using this method makes it a promising drying technique.
