Patent

CA 2211777

The present invention relates to acrylate-based, associative polymeric rheology modifier prepared by polymerization of a C1-C6 alkyl ester of acrylic acid and/or a C1-C6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di- (C1-C4)alkylamino (C1-C4)alkyl (meth)acrylate, a mono or di-(C1-C4)alkylamino (C1-C4)alkyl (meth)acrylamide, and an associative monomer.

La présente invention concerne un modificateur polymérique des propriétés rhéologiques associatif à base d'acrylate préparé par polymérisation d'un ester alkylique en C1-C6 de l'acide acrylique et/ou d'un ester alkylique en C1-C6 de l'acide méthacrylique, un monomère choisi parmi les composés hétérocycliques substitués par un vinyle contenant au moins un atome d'azote ou un atome de soufre, du (méth)acrylamide, un (méth)acrylate de mono- ou de di- (C1-C4)alkylamino (C1-C4)alkyle, un (méth)acrylamide de mono ou di-(C1-C4)alkylamino (C1-C4)alkyle et un monomère associatif.
