Abstract
A lubricating oil has dissolved therein a dispersing agent comprising a graft polymer, prepared in the presence of a free radical catalyst, of (1) a preformed oil-soluble homo- or copolymer of acrylic or methacrylic acid esters, and (2) an ethylenically unsaturated monomer containing a tertiary nitrogen atom, the graft polymer containing 2 to 30% by weight, based on the weight of polymer (1), of the monomer (2). In examples (1) is a copolymer of methyl methacrylate and methacrylic acid esters of fatty alcohols and (2) is N-vinyl pyrrolidone.ALSO:A preformed oil-soluble homo- or copolymer of acrylic or methacrylic acid esters is subjected to graft polymerization with an ethylenically-unsaturated monomer containing a tertiary nitrogen atom in the presence of a free-radical catalyst, whereby a graft polymer is formed containing 2 to 30% (based on the weight of preformed polymer) of the said monomer. The preformed polymer may be prepared in bulk or emulsion, followed by dispersion in the N-containing monomer, or prepared in solution e.g. in oil and said monomer added thereto. Specified base polymers are homopolymers of acrylic and methacrylic acid esters of alcohols containing at least 8 carbon atoms and copolymers of these monomers with esters of fumaric or itaconic acid and alcohols containing 8 to 18 carbon atoms, with vinyl acetate, or with compounds of which the homopolymers are oil-insoluble e.g. acrylic and methacrylic acid esters of alcohols with 1 to 4 carbon atoms, or with aminoalkyl esters e.g. dimethyl aminoethyl methacrylate, di-n-butylaminoethyl acrylate, dimethylaminobutyl acrylate and n-butylaminoethyl methacrylate. The tertiary nitrogen-containing monomer is e.g. an N-vinyl lactam such as N-vinyl-2-pyrrolidone, N-vinyl-caprolactam, N - vinyl - 3 - methyl pyrrolidone, N-vinyl - 5 - piperidone and N - vinyl - 4 - n-butyl caprolactam or the corresponding thiolactams. Cyclic N-vinyl imides e.g. N-vinyl succinimide, N-vinyl-a -methyl succinimide and N-vinyl phthalimide may be used as can N-vinyl oxazolidones and N-vinyl carboxylic acid amides e.g. N-vinyl-N-ethylacetamide and N-vinyl-N-methyl benzamide. The free radical catalyst is e.g. azodiisobutyronitrile, tertiary butyl perbenzoate or tertiary butyl hydroperoxide. The aminoalkyl esters specified above may be grafted on to the preformed polymer along with the tertiary nitrogen containing monomer. In the examples, the monomer used is N-vinyl pyrrolidone, together with N-dimethylaminoethyl methacrylate in Example 3. The base polymer is a copolymer of methyl methacrylate and a mixture of methacrylic acid esters of fatty alcohols and the catalyst is tertiary butyl perbenzoate.
