Oil-soluble reaction products of intermediate (a) from a high molecular weight olefin polymer, acetonitrile, and chlorine with (b) a piperazine, and lubricant compositions containing the same

Claim 1

The oil-soluble product prepared by the process comprising, preparing intermediate A by reacting from about 0.3 moles to about 2.5 moles of a high molecular weight olefin polymer having an average molecular weight of at least about 600, with from about 0.5 moles to about 7.5 moles of acetonitrile and from about 0.4 moles to about 2.0 moles of chlorine or bromine in the presence of a catalytic amount of iodine in the absence of light at a temperature of from about 60° to about 160°F. and thereafter reacting intermediate A with piperazine or with (b) an N-aminoalkyl-substituted piperazine at a temperature of from about 200° to about 350°F. for about 1-6 hours, said amine being used in an amount to provide sufficient amine groups to replace the halogen atoms in said intermediate (A).
