Ethylene copolymer viscosity index improver-dispersant additive useful in oil compositions
TL;DR: In this article, the grafting reaction was carried out thermally, or more preferably with a free radical initiator such as a peroxide in a mineral lubricating oil, in which case the acid component, preferably also acts to solubilize insoluble compounds formed by side reactions, such as maleic anhydride grafted oil molecules reacted with amine, to thereby inhibit haze formation.
