본 발명은 메타크릴산의 없이 적어도 네 개의 단량체로부터 제조된 가교된 설폰화 아크릴 공중합체 P를 제공한다. 본 발명은 또한 점탄성 및 현탁 특성을 갖고 상기 공중합체 P를 포함하는 수성 조성물 C의 제조를 포함한다. A crosslinked, sulphonated, acrylic copolymer may be prepared from at least four monomers and in the absence of methacrylic acid. Such a copolymer may be prepared into an aqueous composition having viscoelastic and suspensive properties, including such a copolymer. Such copolymer(s) may include, in polymerized form: (a) an anionic monomer comprising acrylic acid and/or an acrylic acid oligomer, optionally in salt form; (b) a non-ionic monomer comprising styrene, a C1-C8 acrylate ester, and/or a C1-C8 methacrylate ester; (c) a compound comprising 2-acrylamido-2-methylpropane sulfonic acid, 2-sulfoethyl methacrylate, sodium methallyl sulfonate, and/or styrene sulfonate, optionally in salt form; (d) a cross-linking compound or compound including a first and a second polymerizable olefinic unsaturation, wherein the copolymer comprises no methacrylic acid
