Thiocarbonate compounds which, in one embodiment, are utilized as a rheology modifier or associative thickener. The thiocarbonate compounds thicken or increase the viscosity of a composition, preferably an aqueous composition when used in an effective amount. In one preferred embodiment, the thiocarbonate compounds include at least one hydrophilic group containing repeat unit such as derived from acrylic acid, and at least one hydrophobic group to enhance association with other compounds and thus increase viscosity of a composition. Aqueous composition comprising a latex and thiocarbonate associative thickeners are described.
Thiocarbonate化合物在一种实施方式中被用作流变改性剂或联合
增稠剂。当以有效量使用时,这些thiocarbonate化合物可以增稠或增加组成物的粘度,特别是
水性组成物。在一个优选实施方式中,这些thiocarbonate化合物包括至少一个亲
水基团重复单元,例如来自
丙烯酸,并且至少一个疏
水基团,以增强与其他化合物的结合,从而增加组成物的粘度。描述了包含乳胶和thiocarbonate联合
增稠剂的
水性组成物。
