摘要： The present invention relates to additives for lubricating oils, constituted by a copolymer prepared from 35-55%, and preferably 40-50%, of substituted or non-substituted styrene monomers, and from 65-45%, and preferably 60-50% of heavy C.sub.12 -C.sub.20 alkyl esters of methacrylic acid, of which at least 80% consist of C.sub.16 -C.sub.20 alkylmethacrylates, said copolymer having a polydispersity which is as low as possible, a parameter of solubility close to that of the oil for which the additives are intended and a molecular weight of between 80,000 and 200,000 and being able, moreover, to be modified by a comonomer and vinyl compounds. One application of the invention is the formulation of lubricating oils.

摘要： This invention relates to compounds of formula Q--O--R--O--Q wherein Q represents a substituted or unsubstituted 2-(2-hydroxybenzyl) phenyl group, and R is a residue of a di- or tri-basic, organic or inorganic acid. Compounds in accordance with the invention can be used as stabilizers for plastics materials, in particular to provide them with thermal stability and stability against ultra violet light. The low volatilities of these compounds compared with the analogous di-phenols Q--O--H render them of particular value.
