摘要:
The use of copolymers obtained by free-radical polymerization of a mixture of i) 30 to 80% by weight of N-vinyllactam, ii) 10 to 50% by weight of vinyl acetate, and iii) 10 to 50% by weight of a polyether, with the proviso that the total of components i), ii) and iii) equals 100% by weight, as solubilizers for slightly water-soluble substances.
