Abstract:
1. A process for producing aqueous latices by emulsion polymerization, the process comprising: mixing one or more monomers with a gel-phase-free emulsifier system, wherein the gel-phase-free emulsifier system comprises an aqueous solution, and wherein the aqueous solution comprises one or more nonionic surfactants, and wherein the nonionic surfactants are selected from the group consisting of: (a) the addition products of from 1 to 40 mol of ethylene oxide and/or propylene oxide per mole onto allyl alcohol, and (b) the addition products of from 1 to 40 mol of ethylene oxide and/or propylene oxide per mole onto allyl alcohol, where the OH group of these addition products is terminally capped in the sense that it is replaced by a group OR, where R is an alkyl radical having 1 to 20 carbon atoms which may be saturated or unsaturated, straight-chain or branched, and wherein the emulsifier system further comprises one or more surfactants which are selected from the group consisting of: (c) the compounds of the formula R (d) the compounds of the formula R (e) the compounds of the formula H—O—X—H, where X is a segment which is composed of 1 to 40 ethylene oxide and/or propylene oxide units linked together.
