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.
