Alkoxyamines containing a vinyl group, their applications and methods of their production

Alkoxyamines containing a vinyl group as represented by the following general formula (1) are produced in a method which comprises a process of heating divinyl benzene, nitroxide compound and organic peroxide up to a temperature at which the organic peroxide decomposes thermally: ##STR1##

(In the formula, R¹ represents an aryl group or an R²O group, wherein R² represents a linear or branched alkyl group having 1-12 carbon atoms or a cycloalkyl group. R³ and R⁴ are each tertiary alkyl group having 4-6 carbon atoms or of cyclic structure where R³ and R⁴ are connected with each other having a total carbon number of 8-16. In case of cyclic structure, they are optionally substituted either by an alkyl group, an oxo group, a hydroxyl group, an acyloxy group or an alkoxy group.) Furthermore, graft polymers can be produced by the use of high molecular radical polymerization initiators from which an alkoxyamine group suspends.
