    摘要: Copolymers for use in solubilizing substances which are insoluble in water, substances which are only sparingly soluble in water, and combinations thereof; such copolymers comprising: (a) 60 to 99% by weight of N-vinylcaprolactam; and (b) 1 to 40% by weight of at least one other monomer selected from the group consisting of: C8-C30-alkyl esters of monoethylenically unsaturated C3-C8-carboxylic acids; N—C8-30 alkyl-substituted amides and N,N—C8-30 dialkyl-substituted amides of acrylic acid, methacrylic acid, or combinations thereof; vinyl esters of aliphatic unbranched C8-C30-carboxylic acids; C8-C30-alkyl vinyl ethers; and mixtures thereof.
