ABSTRACT:
Gel-free dispersant additives for lubricating and fuel oil compositions comprise at least one adduct of (A) .alpha.-olefin homopolymer or interpolymer of 700 to 10,000 number average molecular weight, free radically grafted with an average of from about 0.5 to about 5 carboxylic acid producing moieties per polymer chain, and (B) at least one non-aromatic nucleophilic post-treating reactant selected from (i) amine compounds containing only a single reactive amino group per molecule, (ii) alcohol compounds containing only a single hydroxy group per molecule, (iii) polyamine compounds containing at least two reactive amino groups per molecule, (iv) polyol compounds containing at least two reactive hydroxy groups per molecule, (v) aminoalcohol compounds containing at least one reactive amino group and at least one reactive hydroxy group per molecule, and (vi) mixtures of (i) to (v); provided that when said post-treating reactant includes one or more of (iii), (iv) or (v), the reaction between (A) and (B) is conducted in the presence of sufficient chain-stopping or end-capping co-reactant (C) to ensure that the grafted and post-reacted product mixture is gel-free.
