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.

Abstract: A battery electrolyte solution contains a lithium salt dissolved in a solvent phase comprising at least 10% by weight N of (2,2-difluoroethyl) ethyl carbonate. The solvent phase comprises optionally other solvent materials such as 4-fluoroethylene carbonate and other carbonate solvents. This battery electrolyte is highly stable even when used in batteries in which the cathode material has a high operating potential (such as 4.5V or more) relative to Li/Li+. Batteries containing this electrolyte solution therefore have excellent cycling stability.

Abstract: The present invention relates to a process comprising the step of contacting an aqueous dispersion of swelled polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L. The swelled polymer particles arise from neutralization of alkali swellable polymer particles having a high acid core content and a low Tg shell. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.
