    摘要: The present invention provides a novel high-molecular substance having a unique function and a process for producing the same. That is, it is a poly(meth)acrylamide which has a syndiotacticity of 50% or lower and is highly isotactic or heterotactic. The poly(meth)acrylamide is obtained by radical-polymerizing an acrylamide or methacrylamide in the presence of a Lewis acid catalyst.

    摘要: Controlled architecture polymers made preferably with acrylamide type monomers are prepared in living-type or semi-living-type free radical polymerizations, with the architecture preferably being other than linear, such as star, branched, grafted or hyper-branched. The controlled architecture polymers have high weight average molecular weights and low viscosities, which make they particularly useful in replaceable capillary electrophoresis separation media for biological molecules, such as DNA fragments.
