    Abstract: The tendency of an oil to foam is inhibited by adding to the oil a homopolymer derived from a silane monomer of formula wherein R is a C1-C18 monovalent hydrocarbon group comprising an alkyl, cycloalkyl, aryl, aralkyl or alkaryl group, R1 is a C1-C18 alkyl or alkyloxyalkyl group, R11 is a vinyl, allyl or cyclohexenyl group, x is 0, 1 or 2, y is 1, 2 or 3 and the sum of x and y is 3. Polymerization takes place through the R11 groups to produce a carbon-to-carbon chain, so that the polymers are not polysiloxanes. The oil may be a mineral or synthetic lubricating oil or a ligher petroleum fraction such as gasoline or kerosene. Synthetic lubricating oils mentioned are polymerized unsaturated hydrocarbons (e.g. polybutenes, polypropenes and mixtures of these), polyalkylene glycols and esters thereof, and the aliphatic diesters of dicarboxylic acids (e.g. butyl, hexyl, 2-ethylhexyl, decyl and lauryl esters of sebacic, adipic or azelaic acid). The homopolymers may be derived from vinylalkoxy-, allylalkoxy- or cyclohexenylalkoxy-silanes or mixtures of these. In particular, homopolymers derived from vinyltriethoxy-, vinyltributoxy-, vinylbutyldiethoxy-, vinyldibutylethoxy-, vinylhexyldibutoxy-, vinyldiphenylethoxy-, vinylphenyldiethoxy-silane may be employed. The homopolymers may be employed in lubricating oils in conjunction with other additives, such as extreme pressure agents, viscosity index improvers, oiliness agents and detergents. Specified detergents are phosphosulphurized hydrocarbons (e.g. phosphosulphurized polybutylene) neutralized with sodium or potassium hydroxide, alkaline earth petroleum sulphonates, alkaline earth phenyl stearates and alkaline earth alkyl phenol sulphides. In the examples, toluene or kerosene solutions of polyvinyltriethoxysilanes are added to a lubricating composition consisting of mineral oil and lecithin. For comparison purposes, the effect of adding toluene or kerosene solutions of dimethylsilicones to the same lubricating composition is described.ALSO:Homopolymers derived from a silane monomer of formula wherein R is a C1-C18 monovalent hydrocarbon group comprising an alkyl, cycloalkyl, aryl, aralkyl or alkaryl group, R1 is a C1-C18 alkyl or alkoxyalkyl group, R11 is a vinyl, allyl or cyclohexenyl group, x is 0, 1 or 2, y is 1, 2 or 3 and the sum of x and y is 3, are employed in oils as anti-foam agents (see Group III). Polymerization takes place through the R11 groups to produce a carbon-to-carbon chain, so that the polymers are not polysiloxanes. The monomers may be polymerized at elevated temperature and in the presence of di-t-butyl peroxide as catalyst, employing an inert, substantially anhydrous atmosphere, for example of nitrogen, argon or carbon dioxide. In examples, vinyltriethoxysilane, vinylethyldiethoxysilane, vinylphenyldiethoxysilane or vinyldiphenylethoxysilane are polymerized.
