The radical polymerization of various (meth)acrylamides in the presence of Lewis acids such as Yb(OTf) 3 and Y(OTf) 3 was carried out. The polymerization with Lewis acids led to highly isotactic polymers, while the polymers synthesized without Lewis acids were atactic or syndiotactic. The dependence of the polymer properties on the tacticity was also demonstrated.
