摘要：

The radical polymerization of the N-monosubstituted methacrylamides, MMAM and IPMAM, was carried out in the presence of Lewis acids. Yb(OTf)3 significantly increased the isotacticity (mm) of the obtained polymers. The phase-transition temperature of poly(IPMAM) in water clearly depended on the tacticity of the polymer.
