Abstract

Inventia se refera la o suspensie stabila de polimeri hidrosolubili, constituita din 40...15+ parti în greutate polimer, ales dintre poliacrilamida partial hidrolizata, polizaharida, copolimer acrilamida - acod acrilic, 100 parti în greutate hidrocarbura alifatica sau aromatica cu 5...30 atomi de carbon, 0,1...5 parti în greutate agent tensioactiv. Procedeul pentru obtinerea suspensiei stabile consta în introducerea în mediul hidrocarbonat lichid a agentului de îngrosare si, eventual a agentului tensioactiv, dupa care amestecul se reîncalzeste la 40...150 degree C, timp de 5 min...1 h si apoi se raceste pîna la 40 degree C, în final, adaugîndu-se progresiv polimerul hidrosolubil.
