SYNTHESIS OF СОPOLYMERS OF C12–C16 ALKYLMETHACRYLATES WITH STYRENE AND INVESTIGATION OF THEM AS VISCOUS AND DEPRESSANT ADDITIVES

E.U.Isakov

The synthesis has been made of copolymers of C₁₂–C₁₆alkylmethacrylates with styrene, possessing thickening and depressing properties in composition of petroleum oils. Conditions providing production of copolymers with required characteristics are found. The influence of synthesized copolymers on viscosity-temperature and depressant properties of oils has been studied. The recommendation on using investigated copolymers as bifunctional additives are made.

Keywords : copolymerization, alkylmethacrylates, styrene, viscous additives, depressant
