The influence of ethylene/alpha-olefin copolymers used as additives on the viscosity and low-temperature properties of mineral oils
Abstract
Ethylene/a-olefin copolymers (M < 20 000) (PEAOP) were studied as depressants and viscosity improvers, at concentrations of 0.5 and 1% by wt., in (a) industrial oil I—20A and (b) motor oil M-11. The pour points of the oils fell (a) by 15°C and 25°C, and (b) by 6°C and 10°C, respectively. Slovenian Viskocryl-100 was found to be equivalent and superior to the copolymer additive as depressant for the I-20A and the M-11, respectively (Table 2). Russian PMA-D was inferior as depressant. Kinematic viscosity and viscosity index of the oils were studied in relation to additive content (Table 3).
