Abstract: The present disclosure relates to methods of forming a surfactant composition, the method comprising: combining a C12-14 aliphatic straight chain alcohol, and a C10 aliphatic branched chain alcohol in a single reaction vessel to provide an alcohol mixture. The C12-14 aliphatic straight chain alcohol and the C10 aliphatic branched chain alcohol may be combined in a ratio of from about 0.8:1 to 1.4:1. The alcohol mixture may be ethoxylated to provide a surfactant composition. As a measure of the detergent performance of the surfactant composition, a stained fabric subjected to a laundry wash trial with the surfactant composition may exhibit a reflectance at 460 nm that is within 5% of a reflectance observed at 460 nm on a stained fabric subjected to a laundry wash trial with a reference composition comprising a 1:1 physical mixture of ethoxylated alcohols.

Abstract: An emulsion polymerization process of manufacturing a graft polymer composition with a reduced residual monomer content includes feeding a vinyl aromatic monomer, an unsaturated nitrile, and a first portion of an initiator to a reactor having a temperature of 50 to 63° C., the reactor containing an initial reaction system comprising water and a diene emulsion. After 10% to 35% of the first portion of the initiator has been added, the reactor temperature is increased to 65 to 85° C. The polymerization reaction runs for 0 to 30 minutes, then a second portion of the initiator and a third monomer are added, and the reaction is allowed to proceed for a second non-charging reaction time to produce the graft polymer composition. In the process, the vinyl aromatic monomer and the unsaturated nitrile are fed to the reactor in 10 to 40 minutes. The process time can be less than 145 minutes.
