摘要：
The stereodirecting influence of a thermally activated synthetic hydrotalcite material on the polymerization of propylene oxide has been demonstrated. Racemic propylene oxide can be polymerized to yield a crystalline, isotactic polymer fraction and a liquid, atactic fraction. (S)-(-)propylene oxide, under similar conditions, yields an optically active crystalline fraction and a liquid fraction of considerably reduced optical activity. Both liquid fractions exhibit a high degree of regioirregularity in the polymer chain. © 1991.
