Description

Изобретение относитс  к получению полимерной композиции па основе полиоксиэтиле«а и стабилизатора. Известна тюлимерна  композици  на основе полиоксиэтилена и стабилизатора - пипера- 5 зина. Однако применение пиперазина в качестве стабилизатора не обеспечи Бает термостабильности лолиоксиэтилена и ето водных растворов .10 Целью насто щего изобретени   вл етс  повышение стабилизирующего эффекта полимерной КОМ1ПОЗИЩИИ на основе полиоксиэтилена. Эта цель достигаетс  тем, что в качестве стабилизатора в ней использован диметилди «- (р-нафтиламино)-фенокси -силап (С-41) в количестве 0,01-5%; от веса полимера. Добавка С-41 к иолиоксиэтилену уменьшает снижение молекул рного веса при прогреве полимера в течение 3 суток при 70°С в два раза, go Водные растворы стабилизированного полиоксиэтилена более устойчивы, чем нестабили .зированного при прогреве 0,3%-ного раствора при 70°С в течение 25 час отно,сительна  в зкость снижаетс  -с 2-7 до 1,6 дл  нестабили- 95 .зированного и до 2,2 дл  стабилизированного. Пример 1. 2 т полиоксиэтилена молекул рного веса 2,9-10« смешивают с 0,002 или 0,02 г С-41 на скоростной мельнице. Затем прогревают исходный п стабилизированный зо 15 лиоксиэтилен на воздухе при 70°С в течение суток. Результаты представлены в табл. 1.

Результаты испытаний приведены в табл. 2. т а б л ц а 2 Вли ние С-41 на снижение относительной в зкости 0,3%-ного раствора полиоксиэтилена в воде Без стабилизатора2,831,15 1% С-412,712,01 3 Предмет изобретени  Полимерна  композици , состо ща  из по- . лиоксиэтилена и стабилизатора, отличающа с  тем, что, с целью повышени  стабилизи- 5 4 рующего эффекта, в качестве стабилизатора вмей использован диметилди- л-(р-иафтиламиио )-фе1юкси -сила11 в количестве 0;01-5% от. веса полимера. The invention relates to the preparation of a polymeric composition on a polyoxyethyl base a and a stabilizer. The polyoxyethylene based stabilizer and piperazine stabilizer is known. However, the use of piperazine as a stabilizer does not ensure the thermal stability of lioxyethylene and this is aqueous solutions. 10 The aim of the present invention is to increase the stabilizing effect of polyoxyethylene based polymer. This goal is achieved by using dimethyldi "- (p-naphthylamino) -phenoxy-sylap (C-41) in an amount of 0.01-5%; by weight of polymer. The addition of C-41 to iolioxyethylene reduces the molecular weight decrease when the polymer is heated for 3 days at 70 ° C twice, go Aqueous solutions of stabilized polyoxyethylene are more stable than non-stabilized during heating of a 0.3% solution at 70 ° C for 25 hours of relative viscosity decreases from –– from 2–7 to 1.6 for unstabilized and to 2.2 for stabilized. Example 1. 2 tons of polyoxyethylene molecular weight 2.9-10 "is mixed with 0.002 or 0.02 g C-41 in a high speed mill. Then, the initial p stabilized zooloxyethylene is heated in air at 70 ° С during the day. The results are presented in table. 1. Table 1 of V.li n11e C-41 for reducing the molecular weight of polyoxyethylene Without stabilizer 2.9, 1% C-412.9 P & M 2. 2. Prepare 0.3% aqueous rasters of polyoxyethylene with C- 41 and without it, and projected them for 25 hours at 70 ° C. The test results are shown in Table. 2. t a lb a 2 Effect of C-41 on reducing the relative viscosity of a 0.3% aqueous solution of polyoxyethylene in water Without a stabilizer 2.831.15 1% C-412,712.01 3 Subject of the invention Polymer composition consisting from- lyoxyethylene and stabilizer, characterized in that, in order to increase the stabilizing effect, dimethyldyl- (p-iaftilamio) -fe1yuxyylyl is used as a stabilizer in the amount of 0; 01-5% of. polymer weight.
