Abstract

The present invention relates to compositions containing hydrolytically stable multi-purpose polymers that are polymerized from a monomer mixture comprising: at least one amino-substituted meth(acrylate) (ASMA) monomer or salt thereof; and at least one nonionic vinyl (NIV) monomer, wherein the monomer mixture optionally comprises one or more of at least one vinyl associative (VA) monomer; at least one vinyl surfactant (VS) monomer; and / or at least one polymerizable silicone macromer (PSM) and wherein the monomer mixture further optionally comprises one or more of at least one crosslinking (XL) monomer; at least one chain transfer agent (CTA); and / or at least one polymeric stabilizer. The multi-purpose polymers of the present invention can also be prepared from monomer mixtures containing chain transfer agents or other functional components commonly utilized in polymerization processes.

Description

technical field [0001] The present invention relates to a multipurpose polymer which is the polymerization product of a monomer mixture comprising at least one amino-substituted meth(acrylate) (ASMA) monomer or a salt thereof; and at least one nonionic vinyl (NIV) monomer, wherein the monomer mixture further comprises one or more of: at least one vinyl associative (VA) monomer; at least one vinyl surfactant (VS) monomer; and / or at least one polymerizable silicone macromer (PSM), and the monomer mixture further optionally comprises one or more of: at least one crosslinking ( XL) a monomer; at least one chain transfer agent (CTA); and / or at least one polymer stabilizer. The multipurpose polymers of the present invention can also be prepared from monomer mixtures containing chain transfer agents or other functional components commonly employed in polymerization processes. In one embodiment, the multipurpose polymers of the present invention have long-term hydrolytic stability (...
