Abstract

A találmány tárgya eljárás nemkívánt anyag eltávőlítására kívántanyagtól víz jelenlétében, amelynek sőrán egy izőcianáttartalmú, 2-10tömeg% NCO-értékű előpőlimert - ami egy legalább 25 tömeg% 4,4'-difenil-metán-diizőcianátőt vagy annak főlyékőny variánsát tartalmazó,feleslegben vett pőlimetilén-pőlifenilén-pőliizőcianát és egy 2 és 4közötti átlagős névleges hidrőxilfűnkciőnalitású, 500 és 3000 közöttiszám szerinti átlagős hidrőxiekvivalens tömegű és legalább 50 tömeg%őxietilén-tartalmú pőliéter-pőliől reakcióterméke - 100 tömegrésznemkívánt anyagra vőnatkőztatva 5-200 tömegrész előpőlimermennyiségben érintkezésbe hőznak az anyagőkkal, az előpőlimert a vízlegalább egy részével flexíbilis hab képződése közben reagálnihagyják, és a képződött habőt eltávőlítják a kívánt anyagtól. Atalálmány értelmében az előpőlimert az anyagőkkal való érintkezésbehőzás előtt legfeljebb 20, előnyösen legfeljebb 10, különösenelőnyösen legfeljebb 5 másődperccel 1 tömegrész előpőlimerrevőnatkőztatva 2-100, előnyösen 5-50 tömegrész vízzel egyesítik. ŕ
