Abstract
FIELD: organic chemistry. SUBSTANCE: desired copolymer contains units of acrylamide or (meth)acrylamide, acryl or(meth)acryl acid and nitrile of acryl acid, their ratio (mass %) is (20.0-55.0):(10.0-50.0):(20.0-50.0) respectively. Molecular weight of desired copolymer is 2,5•10-2,5•10. Said copolymer may be used as modifying agent for drilling solutions and as stabilizing agent for mineral dispersions. EFFECT: improves quality of desired product.
