Abstract

This paper presents a calculation method of intrinsic viscosity of copolymers in different solvents and oil SAE 10W, Huggins and Schulz-Blascheke coefficients, of two copolymers used as viscosity improvers for multi-grade oil. Intrinsic viscosities were determined from the dependence of reduced viscosity on polymer concentration and their extrapolation to zero polymer concentration. Huggins and Schulz- Blascheke coefficients of two copolymers were determining their intrinsic viscosity.
