Title: Process for producing cationic latexes
Abstract:
A process for producing cationic synthetic rubber latexes by the emulsion polymerization of a conjugated diene or a conjugated diene and a comonomer copolymerizable with the conjugated diene, wherein the polymerization is carried out in the presence of a cationic emulsifier consisting of one or more organic or inorganic acid salts of a .beta.-hydroxy- or .beta.-hydroxymethyl-alkylpolyamine of the general formulae: ##STR1## wherein X is a hydroxyl or hydroxymethyl group, R.sub.1 is a hydrogen atom or an alkyl group of 1 to 20 carbon atoms, R.sub.2 is a hydrogen atom or an alkyl group of 1 to 20 carbon atoms, R.sub.1 + R.sub.2 together contain 8 to 20 carbon atoms, and n is an integer of 1 to 3, an ethylene oxide and/or propylene oxide adduct thereof, or an organic or inorganic acid salt of such an adduct, or a mixture thereof, and in the presence of colloidal alumina.
