IRRADIATION FACTOR-DEPENDENCY. SOME VINYL MONOMERS: MULTIPLE PARAMETERS
Abstract
The effect of fifteen factors, singly or combined, on vinyl monomers are presented. The monomer systems used in this study were acrylonitrile, butyl acrylate, styrene, vinyl acetate, acrylonitrile-styrene, butyl acrylatestyrene, vinyl acetate-styrene, acrylonitrilevinyl acetate, butyl acrylate-vinyl acetate, and 1,1,3-trihydroperfluoropropyl acrylate. From the data presented in the report it was concluded that the effect of: (1) air on a degassed system is dependent on the monomer system; (2) flame-out of the tubes is dependent on the monomer system; (3) degassing once, twice, or three times is dependent on the monomer system; (4) the combination of flame-out and degassing is also dependent on the monomer system; and (5) heating at 75 C in combination with 3 flame-outs and 3 degassings is significantly more effective in increasing the amount of polymer in the 8 systems studied than is the use of a temperature of 25 C. An indication was also observed that a minimum amount of both moisture and oxygen may be desirable for optimal polymerization of certain monomers with a given set of parameters.
