    Abstract: A lubricant which comprises: a mineral oil basestock which has been dewaxed via catalytic cracking and/or catalytic isomerization; an alkylene-alkylene copolymer; and a lubricating oil flow improver formed from the reaction product of: (a) an unsaturated carboxy ester formed via the esterification of an unsaturated carboxylic acid or its corresponding anhydride with a monohydric aliphatic alcohol having an average carbon number of between about 10 to 18, the unsaturated carboxy ester having the formula: wherein R' is selected from the group consisting of hydrogen and COOR and wherein R is a C6 to C22 alkyl group; and (b) a monomer selected from the group consisting of (i) a vinyl ester having the formula: wherein R1 comprises an alkyl group containing from 1 to 18 carbon atoms; (ii) an olefin having the formula wherein R1 and R2 can independently be hydrogen, an alkyl having from 1 to 28 carbon atoms, or a substituted aryl group, provided both R1 and R2 are not hydrogen, the reaction product having a specific viscosity in the range between about 0.3 to 1.5, or a weight average molecular weight of between about 50,000 to 350,000 Daltons.

    Abstract: Additives for improving the low temperature flow properties of hydrocarbon oils are disclosed, which comprise the condensation reaction product of alkylated phenol and aldehyde, wherein: (a) the polymer composition has a number average molecular weight of at least 3,000 and a molecular weight distribution of at least 1.5; (b) in the alkylated phenol reactant the alkyl groups (i) are essentially linear, (ii) have between 6 and 50 carbon atoms, and (iii) have an average number of carbon atoms between 12 and 26, and (c) not more than 10 mole % of the alkyl groups on the alkylated phenol have less than 12 carbon atoms and not more than 10 mole % of the alkyl groups on the alkylated phenol have more than 26 carbon atoms. The additives may also be sulphurised or produced in a branched backbone form in which monomer reactants are copolymerised with certain tri- or tetrafunctional comonomers. Blends of these additives with various hydrocarbon oils, and particularly various middle distillates and lubricating oil compositions, whose low temperature flow properties are significantly improved thereby, are also disclosed. e
