The invention relates to a copolymerizable emulsifier comprising (meth)acrylic acid esters, selected from compounds of the general formula (1) and (II), where: A is an acrylic group having 3 to 40 carbon atoms, x and y independently of each other are a hydrogen group or a methyl group, B is hydrogen or a sulfate or phosphate group, and n a number in the range of 0 to 40. The invention further relates to methods of using said copolymerizable emulsifier in the emulsion polymerization of olefinically unsaturated monomers to prepare polymers.
摘要:
Surfactant compositions which comprise (i) 10 to 90% by weight of one or more compounds selected from the group (a) to (e), and (ii) 10 to 90% by weight of water, based on the composition, are disclosed, where the compounds (a) to (e) are defined as follows: (a) addition products of ethylene oxide and/or propylene oxide with allyl alcohol, (b) addition products of ethylene oxide and/or propylene oxide with allyl alcohol, terminally capped with C1-20 alkyl, (c) compounds of the formula R1—O—X—R2, where X is 1 to 40 ethylene oxide and/or propylene oxide units and where R1 and R2 independently are C1-20 alkyl, excluding allyl, (d) compounds of the formula R3—O—X—H, where X is 1 to 40 ethylene oxide and/or propylene oxide units and where R3 is C1-20 alkyl, excluding allyl, (e) compounds of the formula H—O—X—H, where X is 1 to 40 ethylene oxide and/or propylene oxide units. The surfactant compositions are liquid and pourable at 20° C., with a pour point below 0° C., and are useful as emulsifiers in emulsion polymerization.
