摘要:
Fungicidal solutions containing 2,4,5,6-tetrachloroisophthalodinitrile are provided. The solutions are prepared by dissolving from 5% to 12% by weight of 2,4,5,6-tetrachloroisophthalodinitrile in 1,3-dimethyl-2-imidazolidinone. The solutions are clear and can be stirred without streaking or sedimentation into water-based paints or lacquers or solvent-containing paints or lacquers.

摘要:
The invention herein relates to the preparation of solution polymerizates of acrylic and methacrylic esters. More particularly, this invention relates to a process for the preparation of solution polymerizates of acrylic or methacrylic acid esters of alcohols wherein acrylic or methacrylic monomers are polymerized in a solvent of high-boiling alcohols of from 8 to 40 carbon atoms and 1 to 6 hydroxyl groups, the total batch to be polymerized containing from about 15 to 85 percent by weight of polymerizable substance, based on the weight of the total batch. This invention also relates to a method of using said solution polymerizates to improve the flow properties of lacquers.
