✦ Synopsis

Optically active S(-)-2-phenethylammonium butadiene 1-carboxylate was prepared and polymerized in methanol, using azobisisobutyronitrile as initiator. The optical rotation, optical rotatory dispersion and circular dichroism spectra of the polymers, before and after removal of chiral amine, have demonstrated that the asymmetric induction occurred in the main chain. An asymmetric inductive polymerization mechanism is discussed.

## Abstract Methacrylic acid polymerized in the solid state leads to a much less syndiotactic polymer than when polymerized in the liquid state. This is taken as additional evidence for the importance of the geometry of the monomer crystal lattice in solid state polymerization. Butadiene‐1‐carboxyl

N-butadiene l-carboxylyl S(-)-ct-phenyl ethyl amine (Bu-I-CPA) was prepared and polymerized in various solvents such as acetonitrile, dimethylformamide (DMF), methanol, dioxane and benzene at 50 Β° using AIBN as initiator. From the i.r. spectra of the polymers, it was confirmed that poly(Bu-l-CPA) wa
