ABSTRACT:
Oil-soluble products, suitable as dispersant additives for lubricants, are obtained by reacting (a) a high molecular weight olefin polymer, having an average molecular weight of at least about 600, with acrylonitrile, a halogen, e.g., chlorine, in the presence of a catalyst, e.g., iodine, (b) reacting the product of (a) with a primary aliphatic amine, (c) reacting the resultant product of (b) with maleic anhydride, and (d) reacting the product resulting from (c) with an aliphatic amine or polyamine containing at least one primary amino group per anhydride function on the product (c).
