Abstract:
1. A process for the production of a vinyl compound of the formula (1), wherein: R —(O—X—O)— represents a moiety of the formula (3) or the formula (4), in which R 8 , R 9 , R 10 , R 14 and R 15 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group and R 11 , R 12 and R 13 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, in which R 16 , R 17 , R 22 and R 23 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, R 18 , R 19 , R 20 and R 21 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, and A is a linear, branched or cyclic hydrocarbon having 20 or less carbon atoms, —(Y—O)— is a moiety of the formula (5) or a random arrangement of at least two kinds of moieties of the formula (5), in which R 24 and R 25 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group and R 26 and R 27 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, Z is an organic group having at least one carbon atom which may contain an oxygen atom, a nitrogen atom or a sulfur atom, and each of a and b is an integer of 0 to 30, provided that at least one of a and b is not 0, which process comprises reacting a bifunctional phenylene ether oligomer of the formula (2) with a vinylbenzyl halide in an aprotic polar solvent in the presence of an alkali metal alkoxide and then adding the reaction solution to a water/alcohol mixed solution to precipitate a solid, in which —(O—X—O)—, —(Y—O)—, a and b areas defined in the formula (1).
