ABSTRACT:
New, highly reactive, polymerizable compounds are described, corresponding to the formula ##STR1## wherein R is H or lower alkyl, Z is a linking entity which is a chemical bond, lower alkylene, lower alkylenedioxy, O or the like, m is an integer 2-3 and n is 0-10. They are prepared by reaction of the corresponding 3(methylthio)phenolic compounds with the appropriate 1,4- or 1,5-alkylene bromide and converting the resulting cyclic sulfonium bromide to the zwitterion by treatment with a strong base anion-exchange resin in hydroxide form. They polymerize in a few minutes at 30.degree.-50.degree. C. to form polymers useful as coatings.
