Abstract: The reaction cycle time for the copolymerization of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerization of methacrylates and acrylates may be dramatically reduced by carrying out the polymerization at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerization which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.

Abstract: As a flow improver in a crude oil or a liquid hydrocarbon fuel are used polymers containing more than one amide group, the amide being an amide of a secondary amine, and either the amide group or an ester group of the polymer containing a hydrogen- and carbon-containing group of at least 10 carbon atoms, provided that if the polymer is derived from the polymerization of an aliphatic olefin and maleic anhydride, the polymer must have both an amide group and an ester group each of which contains a hydrogen- and carbon-containing group of at least 10 carbon atoms, for example, a diamide of a copolymer of an alkyl fumarate, vinyl acetate and maleic anhydride.

Abstract: Improved rate of dissolution in liquid hydrocarbon fuels, of specified tert-butylstyrene copolymers capable of imparting anti-misting characteristics to the fuel, is obtained when the copolymer, following its production by aqueous emulsion polymerization of the monomers, is isolated from the resulting latex by a process of flocculation, separation, washing and drying at moderate temperatures. The copolymer thus isolated is advantageously incorporated in the liquid fuel in the form of a slurry with a hydroxylic liquid and an amine.

Abstract: A process is described for the production of copolymers derived predominantly from a monomer, e.g. tert-butylstyrene, having a very low solubility in water, by low temperature emulsion polymerization in a medium consisting substantially of water alone, under specified reaction conditions; high levels of conversion of monomer are achieved. The copolymer products are useful as additives to liquid hydrocarbon fuels for the purpose of reducing the tendency of the fuels to disseminate into mists under conditions of shock.
