Description
II
Изобретение относитс к синтезу модифнцированных полиамидов (блоксополйамидоэфиров ) с повышенными физико-мехаиическими , термическими и гидролитическими показател ми, пригодных в качестве самоотверждающихс при повышенных температурах без выделени летучих веществ адгезионных, электроизол ционых покрытий, пропиточных материалов и литьевых Компаундов.This invention relates to the synthesis of modified polyamides (block copolyamido esters) with enhanced physicomechanical, thermal, and hydrolytic characteristics suitable as self curing at elevated temperatures without releasing volatile substances of adhesive, electrically insulating coatings, impregnating materials, and casting Compounds.
Известен способ получени модифицированных полиамидов взаимодействием полиамидов с эпоксидсодержащим модификатором .(олигомерными эпоксидноноволачными блоксополимерами) с последующей термообработкой при 200-300°С.A known method for producing modified polyamides by reacting polyamides with an epoxy-containing modifier (oligomeric epoxy-block copolymers) followed by heat treatment at 200-300 ° C.
Теплостойкость этих полимеров не превышает 250 С. Кроме того, модифицированные полиамиды обладают недостаточной гидролитической стабильностью при действии агрессивных агентов и органических растворителей.The heat resistance of these polymers does not exceed 250 C. In addition, the modified polyamides have insufficient hydrolytic stability under the action of aggressive agents and organic solvents.
Целью изобретени вл етс повышение термостойкоЬти и гидролитической стабильности целевых продуктов.The aim of the invention is to increase the heat resistance and hydrolytic stability of the target products.
Цель достигаетс тем, что по предлагаемому способу в качестве полиамидов используют полиамиды общей формулыThe goal is achieved by the fact that the proposed method uses polyamides of the general formula as polyamides.

в качестве эпоксидосодержащего модификатора используют диглицидилевый эфир, 4,4 -диоксидифенилпропана и последующую термообработку провод т при 18О280°С .Diglycidyl ether, 4,4-dioxydiphenylpropane are used as an epoxy-containing modifier and the subsequent heat treatment is carried out at 18 02 280 ° C.
Соотношение (в г) цежду полиамидом и диглицидиловым эфиром 4,4 -диоксидифенилпропана можно измен ть в широких . пределах (5:1 - 1:2,5 соответственно),The ratio (in g) between polyamide and 4,4-dioxydiphenylpropane diglycidyl ether can be varied in wide. limits (5: 1 - 1: 2.5 respectively),
