Patent ID: 8142681

Claim:
A surfactant composition comprising: (i) about 15 to about 20% by weight of one or more compounds selected from the groups (a) and/or (b), wherein (a) and (b) are defined as follows: (a) addition products of from 1 to 40 mol of ethylene oxide per mole of allyl alcohol, (b) addition products of from 1 to 40 mol of ethylene oxide per mole of allyl alcohol, wherein the OH group of these addition products is terminally capped in the sense that it is replaced by a group OR, where R is alkyl having 1 to 20 carbon atoms which may be saturated or unsaturated, straight-chain or branched; (ii) about 35 to about 50% by weight of water, based on the composition; and (iii) about 35 to about 46% by weight a compound of the formula R 1 —O—X—H, where X is a moiety comprising 1 to 40 ethylene oxide units linked together and where R 1 is alkyl having 1 to 20 carbon atoms which may be saturated or unsaturated, straight-chain or branched, with the proviso that R 1 is not allyl, wherein said composition is pourable and liquid at 20° C., with a pour point below 0° C., and wherein said composition is effective as a surfactant for emulsion polymerization.
