Abstract
This invention provides an easily synthesized trivalent organic lanthanoid complex which can be used as a polymerization catalyst for (meth) acrylic monomers. The trivalent organic lanthanoid complex is represented by the general formula (1): 1 wherein M represents Sc, Y or a lanthanide atom, R1 represents a hydrogen atom, a C1-10 alkyl group or a C1-10 alkyl group containing a silicon atom, R2 groups independently represent a C1-10 alkyl group, and n is 1 or 2.
