发明名称 PRECIPITATION POLYMERIZATION OF COPOLYMERS OF A VINYL LACTAM AND A POLYMERIZABLE CARBOXYLIC ACID AND SOLUBILIZATION THEREOF
摘要 <p>A precipitation polymerization process for making copolymers of a vinyl lactam and a polymerizable carboxylic acid in a cosolvent mixture of an aliphatic hydrocarbon solvent, preferably, heptane or cyclohexane, and a secondary alcohol, preferably isopropanol. Copolymers obtained thereby, and others normally insoluble in water, can be solubilized in a mixture of water and an aliphatic oxygen-containing compound.</p>
