Experimental Study on High-Performers Quaternary Copolymer Based on Host–Guest Effect

Experimental Study on High-Performers Quaternary Copolymer Based on Host–Guest Effect

A quaternary polymer (HGP) was prepared by the free-radical polymerization of acrylamide, acrylic acid, maleic anhydride functionalized <i>β</i>-cyclodextrin (MAH-<i>β</i>-CD), and N-(3-methacrylamidopropyl)-N, N-dimethylnaphthalen-1-aminium chloride (NAP). It was found that...
