    • 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, wherein the thus-obtained reaction solution is acidified with a specific amount of an acidic substance, then a salt generated is removed, an alkali substance containing a specific amount of an alkali metal is added to the thus-obtained solution, then a salt generated is removed, and the thus-obtained solution is mixed with water or a water-alcohol mixed solution, to precipitate a solid.
    • 一种有利于生产含有非常少量离子杂质和可水解卤素的乙烯基化合物的方法,其能够通过加热和/或光照固化并得到具有优异介电特性和耐热性的固化产物 该方法可以有效地除去生成的盐,并且包括在碱金属的醇盐的存在下使特定的双功能亚苯基醚低聚物的非质子极性溶剂溶液与乙烯基苄基卤反应,其中将如此获得的反应溶液酸化 与特定量的酸性物质一起除去产生的盐,向所得溶液中加入含有特定量的碱金属的碱性物质,除去所生成的盐,得到的溶液为 与水或水 - 醇混合溶液混合,以沉淀出固体。
