Abstract
A process, advantageous in producibility, for the production of a vinyl compound containing very small amounts of ionic impurities and hydrolysable halogens, which is capable of curing by means of heat and/or light and giving a cured product having excellent dielectric characteristics and heat resistance, which process can efficiently remove a generated salt and comprises reacting a non-protonic polar solvent solution of a specific bifunctional phenylene ether oligomer with a vinylbenzyl halide in the presence of an alkoxide of an alkali metal,
