EFFECT: good processibility of dispersible powders. 10 cl, 1 tbl, 4 ex ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß RU (19) (11) 2 339 592 (13) C2 (51) ÌÏÊ C04B 24/24 C08J 3/02 C08J 3/12 C04B 103/12 C08F 2/12 ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ C08L 31/04 ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ,C08L 29/04 ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2006140515/04, 16.11.2006 (72) Àâòîð(û): ÂÀÉÒÖÅËÜ Õàíñ-Ïåòåð (DE), ÁÀÓÅÐ Âåðíåð (DE) (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 16.11.2006 (73) Ïàòåíòîîáëàäàòåëü(è): ÂÀÊÊÅÐ ÕÅÌÈ Àà (DE) R U (30) Êîíâåíöèîííûé ïðèîðèòåò: 17.11.2005 DE 102005054905.5 (43) Äàòà ïóáëèêàöèè çà âêè: 27.05.2008 (45) Îïóáëèêîâàíî: 27.11.2008 Áþë. ¹ 33 2 3 ...

Recuperating ethylene and vinylacetate from stream of residual gas formed during synthesis of copolymer of vinyl ester and ethylene

FIELD: chemistry. SUBSTANCE: invention relates to a method of recuperating unreacted monomers contained in a stream of residual gas formed during synthesis of a copolymer of vinyl ester and ethylene. Described is a method of producing copolymers containing vinyl ester or ethylene or ethylene unsaturated monomers via radical emulsion or suspension polymerisation in an aqueous medium at absolute pressure between 5 and 100 bars. At the end of polymerisation, the reaction mixture is throttled with reduction of its absolute pressure to 0.1-5 bars. Unreacted monomers are recuperated from the residual gas through multi-step fractionated condensation with deep cooling. At the first condensation step, water vapour is condensed at temperature ranging from -90 to -60°C, and at the third condensation step, ethylene is condensed at temperature ranging from 140 to 100 °C. EFFECT: design of a method which enables extraction of valuable substances from the formed residual gas, where the said substances can be cheaply recycled. 9 cl, 2 dwg, 1 tbl, 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 415 153 (13) C2 (51) МПК C08F 6/10 (2006.01) C08F 2/30 (2006.01) C08F 218/08 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2008129642/04, 14.12.2006 (24) Дата начала отсчета срока действия патента: 14.12.2006 (72) Автор(ы): ГЮНАЛЬТАЙ Мехмет (DE), ЗЕЛИГ Манфред (DE) R U (73) Патентообладатель(и): ВАККЕР ХЕМИ АГ (DE) Приоритет(ы): (30) Конвенционный приоритет: 22.12.2005 DE 102005061576.7 (43) Дата публикации заявки: 27.01.2010 Бюл. № 3 2 4 1 5 1 5 3 (45) Опубликовано: 27.03.2011 Бюл. № 9 (56) Список документов, цитированных в отчете о поиске: ЕР 1420034 А1, 06.11.2003.

Method of producing protective colloid-stabilised polymers

FIELD: chemistry. SUBSTANCE: invention relates to a method of producing aqueous dispersions or powders which are re-dispersible in water. The method of producing protective colloid-stabilised polymers is realised by emulsion polymerisation of one or more vinyl esters of straight or branched alkylcarboxylic acids containing 1-15 carbon atoms with ethylene in a reactor with an external cooling loop, which is equipped with a pump and a heat exchanger, wherein the reaction mixture in the reactor is fed by a pump into a cooled static mixer-heat exchanger with fixed built-in components, and then returned to the reactor. The static mixer-heat exchanger has such parameters where its cooling rate is not less than 50 kW/m 3 of reactor volume. Polymer powder which is re-dispersible in water can be obtained and dried. EFFECT: no significant deposits on the walls of the heat exchanger are observed, efficient heat removal without deterioration of properties of the product. 5 cl, 1 dwg, 2 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 471 810 (13) C2 (51) МПК C08F 2/22 (2006.01) C08F 2/01 (2006.01) C08F 210/02 (2006.01) C08F 218/04 (2006.01) C08F 218/08 (2006.01) B01F 5/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2010111843/04, 11.08.2008 (24) Дата начала отсчета срока действия патента: 11.08.2008 (73) Патентообладатель(и): ВАККЕР ХЕМИ АГ (DE) (43) Дата публикации заявки: 10.11.2011 Бюл. № 31 2 4 7 1 8 1 0 (45) Опубликовано: 10.01.2013 Бюл. № 1 (56) Список документов, цитированных в отчете о поиске: EP 0834518 B1, 24.01.2001.
