摘要： What is described herein are polymerizable pyrrolidonyl 4,5-unsubstituted oxazoline monomers, homopolymers thereof, and copolymers with other monomers. A preferred polymerizable monomer compound is 2-(1-methyl-2-pyrrolidon-4-yl)-2- oxazoline. The polymers herein have excellent hydrotropic properties thus increasing the water solubility of organic compounds previously considered as water insoluble, and exhibit complexation with water soluble consolutes.
摘要翻译：本文所述的是可聚合的吡咯烷酮基4,5-未取代的恶唑啉单体，其均聚物和与其它单体的共聚物。优选的可聚合单体化合物是2-（1-甲基-2-吡咯烷酮-4-基）-2-恶唑啉。本文的聚合物具有优异的水溶助极性，因此增加先前被认为是水不溶性的有机化合物的水溶性，并且与水溶性溶剂呈现络合作用。

摘要： An aqueous process is described for preparing water-resistant coatings of hydrophobic copolymers of a predetermined composition. The hydrophobic copolymers are made from hydrophilic comonomers such as a vinyl lactam and a polymerizable carboxylic acid. The hydrophobic copolymers are rendered water soluble with a volatile neutralizing agent, such as ammonium hydroxide, then coated onto a substrate and heated to provide the water-resistant coating, and, if desired, redissolved in an aqueous alkaline solution.
