Polymerization of 4-Vinylpyridine by Lanthanide Coordination Catalyst

Polymerization of 4-vinylpyridine was carried out with the lanthanide coordination catalyst. The influence of the component in catalytic system and solvents had been examined.The molecular weight of poly(4-vinylpyridinc) obtained in CH2Cl2 with Ln(P204)3/Al(i-Bu)3 is more than 20×104.
