После отгонки растворител , добавки О,3 вес.% этаноламина и фильтровани получают продукты согласно изобретению, обозначенные в таблице буквами А, Б и В.This invention relates to a process for the preparation of polysiloxane polyoxyalkylene block copolymers, which can be used as textile auxiliaries, in cosmetics, as defoamers and demulsifiers for oil-in-water emulsions. A known method of producing polysiloxane polyoxyalkyleneblock copolymer by the interaction of organopolysiloxane containing 5l H groups with a well generalized formula SNg (; and - 1 Y LZ-P where R is metsch, butyl; P is 1; 2; X is chlorine, alkoxystatic with 1-4 carbon atoms, in the presence of a hydrosilylation catalyst, followed by treatment of the obtained polyoxiegigteox propene monool with a molecular weight of 1800-3000 or its mixture with propyl alcohol. The original organopolysiloxanes contain end groups of SiH l. The resulting block copolymers uyuts lack of antifoam activity necks, object of the invention is to increase the activity penostabiliziruyushey polisiloksanpolioksialkilenbloksopolimera object is achieved in that an organopolysiloxane containing SiH groups, a compound of the general formula) for) where P 18-84.; t 1.57-6. 36 Example l.B. as starting material from organopolysipoxane total (I), where p 18; rti 3, which is equilibrated by treatment with sulfuric acid in the amount of 23 g per 1 mol of sipoxane for 12 hours, followed by removal of the acid by repeated washing. The polysiloxane obtained is reacted with dimethviphenylchloride in the presence of a catalyst. The conditions for the performance of the wedding are listed in the table. In this case 1.15 mol of dime is used, type chlorosipane per group Si f 1. The excess of silane is distilled off at. More than 98% of the Si N groups take us in the reaction. The reaction product is reacted with a polyester obtained by addition of propylene and ethylene oxides to n uthanol, and these oxides 7 are gradually added in the form of small blocks — 2, 0 mol to a molecular weight of 182. The end glock consists of propylene oxide units. 58% of the polyoxyalkylene block consists of hydroxypropylene units. The polyether monool is first azeogropically dried. A 10% excess of polyethermonol and 3 liters of toluene per kg of the reaction product are used. At the same time, the amount of ammonia required for binding the released hydrogen chloride is passed through the reaction mixture with stirring. After distilling off the solvent, the additives O, 3% by weight of ethanolamine and filtering receive the products according to the invention, indicated in the table by the letters A, B and B.
