Description

Изобретение относитс  к снособам получени  термостабилизированных полиамидов.This invention relates to methods for the preparation of thermostabilized polyamides.

Известны способы получени  термостабилизированного поли-е-капроамида прибавлением различных ингибиторов термоокислительной деструкции (ароматических аминов, ароматических окси-соединеннй, солей металлов, комплексов металлов и др.) к е-канролактаму перед его полимеризацией.Methods are known for preparing thermostabilized poly-e-caproamide by adding various inhibitors of thermo-oxidative degradation (aromatic amines, aromatic hydroxy-compounds, metal salts, metal complexes, etc.) to e-canrolactam before polymerization.

С целью расширени  ассортимента термостабилизированных нолн-е-капроамидов в качестве ингибитора Предложено примен ть медный комплекс Ы,М-бис - З-окси-2-бензо (Р)-тенилиден -этилендиамина формулыIn order to expand the range of thermostabilized noln-e-caproamides as an inhibitor. It is proposed to use the copper complex L, M-bis-3-hydroxy-2-benzo (P) -tenylidene-ethylene diamine of formula

Способ заключаетс  в прибавлении медного комплекса к е-капролактаму перед его полимеризацией в количестве 0,05-0,1% от веса маномера. Полимеризацию е-капролактама с добавкой комплекса провод т по обычной технологии полимеризации этого мономера в отсутствие ингибитора. Ингибитор хорошо распредел етс  в расплаве полимера, не измен   его в зкостных свойств, не разлагаетс  при температуре полимеризации и не вымываетс  из поли-е-канроамида при мокрых обработках .The method consists in adding a copper complex to e-caprolactam before its polymerization in an amount of 0.05-0.1% by weight of the manomer. Polymerization of e-caprolactam with the addition of a complex is carried out according to the usual technology of polymerization of this monomer in the absence of an inhibitor. The inhibitor is well distributed in the polymer melt, does not change its viscosity properties, does not decompose at the polymerization temperature, and is not washed out of the poly-e-canroamide during wet treatments.

Термостабильность капроновых волокон, содержащих медный комплекс Ы,М-бис- 3-окси2-бензо- (р)-тенилиден -этиленднамина, така  же или в р де случаев превышает термостабильность полиамидных волокон, стабилизированных известными эффективными ингибиторами , например смесью ацетата меди и йодистого кали . В отлнчие от большинства распространенных термостабилизаторов медный комплекс не вызывает окрашивани  канроноRoro волокна при его получении и хранении па свету.The thermal stability of the nylon fibers containing the copper complex N, M-bis-3-oxy2-benzo- (p) -tenylidene-ethylene namin, also, or in a number of cases, exceeds the thermal stability of polyamide fibers stabilized by known effective inhibitors, for example, a mixture of copper acetate and iodide Kali. In contrast to the majority of common heat stabilizers, the copper complex does not cause staining of canonoRoro fibers when it is received and stored in light.

Пример 1. Смесь 150 кг е-капролактама, 0,015% уксусной кислоты, 6% воды и 0,05% медного комплекса Ы,1-бис- 3-окси-2-бензо (р)-тенилиден -этилендиамина натревают в расплавителе при 90°С, перемешива , до образовани  однородного раствора, который далее передавливают в автоклав дл  полимеризации .Example 1. A mixture of 150 kg of e-caprolactam, 0.015% acetic acid, 6% water and 0.05% copper complex N, 1-bis-3-hydroxy-2-benzo (p) -tenylidene-ethylene diamine is melted in a melter at 90 ° C, stirring, until a homogeneous solution is formed, which is then squeezed into an autoclave for polymerization.

Полимеризацию ведут при атмосферном давлении в следуюш,ем режиме: подъем температуры до 248±2°С 2,5 час, выдерживание плава при этой же температуре 8 час. Выгруженный из анпарата в течение 30 мин поли90°С и сушат в вакуум-барабанной сушилке при 120°С и остаточном давлении 5 мм рт. ст. Полученный полимер имеет относительную в зкость раствора 1 г полимера в 100 жл концентрированной серной кислоты 2,24.The polymerization is carried out at atmospheric pressure in the following mode: temperature rise to 248 ± 2 ° С for 2.5 hours, keeping the water at the same temperature for 8 hours. Poly90 ° C discharged from the apparatus for 30 min and dried in a vacuum drum dryer at 120 ° С and a residual pressure of 5 mm Hg. Art. The polymer obtained has a relative viscosity of a solution of 1 g of polymer in 100 g of concentrated sulfuric acid 2.24.

Пример 2. Получение полимера провод т в услови х предыдущего примера, но в присутствии 0,1% медного комплекса. Относительна  в зкость экстрагированного водой и высушенного поли-е-каПроамида 2,40.Example 2.
