摘要：

The radical polymerization of alpha-(alkoxymethyl)acrylates in the presence of a catalytic amount of scandium trifluoromethanesulfonate [initiator: (i-PrOCO2)(2), temp.: 30 degreesC] proceeds in an isotactic specific manner (m approximate to 70%), whereas the syndiotactic (r approximate to 70%) and atactic polymers were obtained during the radical polymerization with a catalytic amount of zinc bromide and without metal salts, respectively. The achievement of opposite sense of stereoregularity (isotactic and syndiotactic) by choosing Lewis acid catalysts during the radical polymerization of alpha-(alkoxymethyl)acrylates was attained to some extent.
