Description
Изобретение относитс к композици м на основе полисульфонов с повышенной текучестью .расплава/ примен емыг1 дл изготовлени , конструкционных деталей в автомобильной, авиационной и других отрасл х промышленности, перерабатываемых литьем под давлением и экструзией. Известна композици на основе поли сульфона и соли щелочного или щелочноземельного металла и оксифосфористой кислоты l . . Однако обработка полйэфирсульфона сол ми сильных оснований и слабой кислоты нецелесообразна, так как полимер мутнеет, темнеет и тер ет текучесть . Известна также композици 2, со держаща полифосфит общей формулы ,) х . ОСИ CHiO где П 2-3. Однако указанный фосфит недостаточно устойчив при хранении (гидроли зуетс и темнеет). Известна также композици на осно ве полйэфирсульфона, содержаща фосфорорганические соединени , напр мер трифенил-(топил)-фосфат, 3-(п-бромфенил )-фосфат, трифенил-(толил)-тиофосфат з . Эти фосфюрорганические соединени не обладают термрстабильностью при температуре переработки полйэфирсульфона (320-380 С). Наиболее близкой по составу вл етс композици С на основе полйэфирсульфона формулы где п 72-90, и фосфитов различного строени , например трифенилфосфита, тринонилфенилфосфита. Однако известные фосфиты недостаточно эффективны и привод т к увели-, чению в зкости расплава полимера при 400°С, т.е. к их структурированию, при этом снижаетс текучесть расплава . Цель изобретени - повыгчение текучести расплава и улучшение перерабатьшаемости композиции на основе полйэфирсульфона формулыThis invention relates to polysulfone-based compositions with a high melt flow / use for manufacturing, structural parts in the automotive, aeronautical and other industries that are processed by injection molding and extrusion. A composition based on poly sulfone and alkali or alkaline earth metal salt and hydroxyphosphorous acid is known. L. . However, the treatment of polyethersulfone with salts of strong bases and weak acid is impractical because the polymer becomes cloudy, darkens and loses fluidity. Composition 2 is also known, containing a polyphosphite of the general formula:). AXIS CHiO where P 2-3. However, this phosphite is not stable enough during storage (hydrolyzes and darkens). A composition based on polyethersulfone containing organophosphorus compounds, such as triphenyl- (topyl) phosphate, 3- (p-bromophenyl) -phosphate, triphenyl- (tolyl) -thiophosphate is also known. These organophosphorus compounds do not have thermal stability at the processing temperature of polyethersulfone (320-380 ° C). The closest in composition is the composition C based on polyethersulfone of the formula where n is 72-90, and phosphites of various structures, for example triphenylphosphite, trinonylphenylphosphite. However, the known phosphites are not sufficiently effective and lead to an increase in the melt viscosity of the polymer at 400 ° C, i.e. to their structuring, thus reducing the fluidity of the melt. The purpose of the invention is to increase the melt flow rate and improve the processability of the composition based on polyethersulfone of the formula
