IRRADIATION FACTOR-DEPENDENCY. SOME VINYL MONOMERS: DEGASSING

Abstract

An evaluation was made of the effect of a single degassing and vacuum or argon on the polymerization of monomer systems by continuous irradiation at 25 C and intermittent irradiation on a 30-min cycle at a temperature of 75 C. The following monomer systems were prepared: acrylonitrile, butyl acrylate, styrene, vinyl acetate, acrylonitrile-styrene, butyl acrylate-styrene, AND VINYL ACETATE-STYRENE. From the results obtained in these studies the following conclusions were drawn: (2) degassing may significantly increase the yield of polymer obtained by irradiation-induced polymerization; and (2) the relative significance of degassing is a function of the monomer system, the dose rate, and the presence of argon.
