-carboxylic acids; (c) 0 to 30% by weight of vinyl acetate; and (d) 0 to 39% by weight of at least one additional free-radically copolymnerizable monomer; wherein the % by weight content of components (a), (b), (c) and (d) totals 100%, and with the proviso that the total amount of component (b) and component (c) combined is 1 to 40% by weight based on the copolymer, are described along with methods of using such copolymers to solubilize substances which are insoluble in water, substances which are only sparingly soluble in water, and combinations thereof.
共聚物包含:(a)60至99重量百分比的至少一种单体,选自N-乙烯基内酰胺、N-乙烯酰胺和它们的混合物;(b)1至40重量百分比的至少一种单体,选自支链的C8-C30脂肪族羧酸的乙烯酯;(c)0至30重量百分比的乙酸乙烯酯;和(d)0至39重量百分比的至少一种额外的自由基共聚单体;其中,组分(a)、(b)、(c)和(d)的重量百分比总和为100%,并且有条件规定组分(b)和组分(c)的总和基于共聚物为1至40重量百分比。还描述了使用这样的共聚物来增溶水不溶性物质、水微溶性物质以及它们的组合的方法。
