Stereocontrol during the polymerization of vinyl monomers is of great importance, because the tacticity of polymers significantly influences their properties and functions. Although radical polymerization has been frequently used for the preparations of various vinyl polymers due to its wide applicability and simple process, the control of the stereochemistry during the polymerization is often not easy, and usually we get atactic polymers.

Poly[(meth)acrylamide]s are some of the interesting polymers due to the unique properties caused by the polar amide group on the side chain. However, the stereospecific polymerization of (meth)acrylamides, expect for anionic polymerization ofN,N-disubstituted acrylamides, had been rarely reported. In 2001, we found that Lewis acids, such as rare earth metal trifluoromethanesulfonates (triflates), are effective for increasing the isotactic-specificity in the radical polymerization of (meth)acrylamides. We also found that the radical polymerization of bulky methacrylamides, such asN-(triphenylmethyl)methacrylamide (TrMAM), proceeds in a highly isotactic manner, and optically active polymers can be produced in the presence of chiral additives. In my lecture, these two different methods of the stereocontrol in the radical polymerization of (meth)acrylamides will be mainly discussed.
