    Abstract: The present invention provides nonionic surfactants, compositions incorporating these surfactants, and related methods of making and using such surfactants and compositions. The nonionic surfactants demonstrate excellent equilibrium and dynamic surface tension properties as well as excellent wetting properties. Further, representative embodiments of the surfactants have shown low foaming characteristics, indicating that the surfactants would be suitable in applications where resistance to foaming is desired. The surfactants can be used singly or in combination with other nonionic and/or ionic surfactants as desired. As an over view, the nonionic surfactants of the present invention have a structure in which the surfactant backbone includes one or more amine moieties. At least one, preferably two or more branched, cyclic, fused cyclic, and/or spyro hydrophobic moieties are pendant from at least one of the amine moieties. Additionally, at least one, preferably two or more hydrophilic moieties, preferably alkylene oxide (i.e., polyether) chains also are pendant from at least one of the amine moieties.

    Abstract translation: 本发明提供非离子表面活性剂，掺入这些表面活性剂的组合物，以及制备和使用这些表面活性剂和组合物的相关方法。 非离子表面活性剂表现出优异的平衡和动态表面张力性能以及优异的润湿性能。 此外，表面活性剂的代表性实施方案已经显示出低发泡特性，表明表面活性剂将适用于需要耐发泡性的应用。 表面活性剂可以根据需要单独使用或与其它非离子和/或离子表面活性剂组合使用。 从过去的观点来看，本发明的非离子表面活性剂具有其中表面活性剂主链包括一个或多个胺部分的结构。 至少一个，优选两个或更多个支链，环状稠合的环状和/或间苯二酚疏水部分从至少一个胺部分侧挂。 此外，至少一个，优选两个或更多个亲水部分，优选环氧烷（即聚醚）链也是至少一个胺部分的侧挂。

    Abstract: The present invention relates to a process for preparing a coatings composition with an open time additive comprising the steps of a) contacting an aqueous dispersion of alkali swellable polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L; and b) neutralizing the alkali swellable particles with a non-volatile base after or upon contact with the rheology modifier and the binder to form swelled multi-staged polymer particles; wherein the alkali swellable polymer particles comprise a shell having a Tg of not greater than 25° C. and an acid functionalized core; and wherein the core-to-shell ratio is in the range of from 1:3.2 to 1:10. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.In another aspect the present invention relates to the preparation of the coatings composition with an open time additive comprising the steps of a) contacting the open time additive with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L, then b) neutralizing the open time additive to form swelled multi-staged polymer particles, wherein the coatings composition with the open time additive exhibits less than a 50% increase in viscosity than the coating composition without the open time additive.
