Изобретение относитс  к синтезу ненасыщенных ариленовых олигомеров.This invention relates to the synthesis of unsaturated arylene oligomers.

Известен способ нолучени  ненасын.ен11ых ариленовых олиго.меров путем взаимадействи  хлорметилированных ариленовых олигомеров (продуктов конденсации производных дифенилоксида) с метакриловой кислотой вA known method for the production of unsaturated alkylene arylene oligo-measures by the interaction of chloromethylated arylene oligomers (condensation products of diphenyloxide derivatives) with methacrylic acid in

В качестве указанных олигомеров используют продукты конденсации хлорметплдифенилоксида с триарилфосфатами, например трифенил- или трикрезилфосфатом, или продукты конденсации хлорметилировапных триарилфосфатов с другими ароматическими соединени ми , например дифенилоксидо.мAs these oligomers, condensation products with chloromethyl diphenyloxide with triaryl phosphates, for example triphenyl or tricresyl phosphate, or condensation products of chloromethyl sulfate triaryl phosphates with other aromatic compounds, for example diphenyloxydio.m are used.

При обработке таких олигомеров избытком метакриловой кислоты в присутствии триэтила .мина происходит замегцепие атомов хлора па метакрилатпые группы.When such oligomers are treated with an excess of methacrylic acid in the presence of triethyl. Min, a tight chain of chlorine atoms and methacrylate groups occurs.

По предлагаемо.му способу реакцию провод т в инepтнo i растворителе при повышенной температуре . Соотношение метакриловой кислоты и триэтиламина выбирают в пределах 1,00-1,55 (лучше 1,05). Смесь кислоты с амипом берут в 5-10-кратном избытке по отпошешпо к содержанию хлора в продукте коидепеации. Способ позвол ет, использу  олпгомерпые продукты конденсации,According to the proposed method, the reaction is carried out in an inert solvent at elevated temperature. The ratio of methacrylic acid and triethylamine is chosen in the range of 1.00-1.55 (better than 1.05). The mixture of acid and amip is taken in 5-10-fold excess by prompting to the chlorine content in the product of co-mineralization. The method allows, using condensed condensation products,
