Abstract and keywords
Abstract (English):
Butadien-nitril'nye kauchuki (BNK) otnosyatsya k elastomeram special'nogo naznacheniya i otlichayutsya povyshennoy stoykost'yu k alifaticheskim uglevodorodnym rastvoritelyam, maslam, toplivu. V zavisimosti ot sootnosheniya monomerov v butadien-nitril'nyh sopolimerah sovmestimost' ih s razlichnymi tipami rastvoriteley i plastifikatorov suschestvenno izmenyaetsya. Krome togo, promyshlennost'yu vypuskayutsya BNK s funkcional'nymi gruppami: karboksil'nymi, gidroksil'nymi, a takzhe gidrirovannye BNK. Cel'yu nastoyaschey raboty yavilsya raschet parametrov rastvorimosti sopolimerov BNK razlichnogo sostava, gidrirovannyh BNK i kauchukov s gidroksil'nymi i karboksil'nymi gruppami. Na osnovanii obrabotki spravochnyh dannyh po ental'piyam ispareniya i mol'nomu ob'emu organicheskih soedineniy iz klassov alifaticheskih i aromaticheskih uglevodorodov, nitrilov, kislot, spirtov i efirov vychisleny inkrementy funkcional'nyh grupp, prisutstvuyuschih v celevyh sopolimerah, i konstanty molekulyarnogo prityazheniya Smolla. Poluchennye inkrementy ispol'zovany dlya rascheta trehmernyh parametrov rastvorimosti sopolimerov, a takzhe zavisimostey izmeneniya svobodnoy energii Gibbsa pri smeshenii ot ob'emnoy doli rastvoritelya dlya dvuh tipov rastvoriteley.
