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.
