emulsion of a polymerized associative acrylic polymer in the presence of polyglycerols and their use as a thickening agent in an aqueous formulation

摘要

"Emulsion of a polymerized associative acrylic polymer in the presence of polyglycerols and their use as a thickening agent in an aqueous formulation" The present invention relates to novel emulsions containing acrylic associative thickeners which, polymerized in the presence of particular polyglycerols, exhibit a remarkably stable thickening power over time. This noticeably reduces the viscosimetric displacement that results from this type of thickener, particularly in low cov rate (volatile organic compounds) or non-covine inks, which appear very quickly after a few days of storage. This guarantees the user identical application properties for his ink, that is, a conserved rheological profile for the ink he formulates and which he applies, regardless of the storage time of said ink, and for a period of up to several months.
