Process for curing at least one monomer to emulsion polymerization, using a mixture tensoativa, mixture tensoativa, and method for manufacturing the mixture tensoativa

摘要

Process for polymerizing at least one monomer under emulsion polymerization conditions, characterized in that the (co)monomers are selected from vinyl aromatic compounds, ethylenically unsaturated carboxylic acids with 3 to 10 carbon atoms, C 1 -C 10 -alkyl esters of ethylenically unsaturated carboxylic acids with 3 to 10 carbon atoms, 1,3-butadiene, and ±-olefins bearing in the range of from 10 to 250 carbon atoms per molecule, in pure form or as mixture with isomers, and using a surfactant mixture comprising (A) an alkoxylation product of at least one alkanol (a), characterized in that alkanol (a) has 6 to 12 carbon atoms per molecule and the average number of alkylene oxide units per molecule in alkoxylation product (A) assumes a value in the range of from 35 to 55, the alkylene oxide units are selected from C 2 -C 10 -alkylene oxide units and alkanol (a) has an average degree of branching of at least 1; and (B) an alkoxylation product of at least one alkanol (b), characterized in that alkanol (b) has 13 to 19 carbon atoms per molecule and the average number of alkylene oxide units per molecule in alkoxylation product (B) assumes a value in the range of from 35 to 55, the alkylene oxide units are selected from C 2 -C 10 -alkylene oxide units, or (C) an alkoxylation product of at least one linear C 12 -C 22 -alkyl alcohol (c), characterized in that the average number of alkylene oxide units per molecule in alkoxylation product (C) assumes a value in the range of from 35 to 55, the alkylene oxide units are selected from C 2 -C 10 -alkylene oxide units.
