    We have previously reported the palladium-catalyzed cyanoesterification of norbornene derivatives with ethyl cyanoformate. Herein we report that the same reaction of norbornadiene with various alkyl cyanoformates (alkyl = Me, Et, nPr, iPr, nBu, tBu, and Bn) can smoothly undergo to afford doubly polar functionalized norbornene derivatives. This reaction is a novel and efficient method to obtain a monomer having both cyano and ester groups with exo-selectivity. The formed norbornene derivatives were polymerized through ring-opening metathesis polymerization (ROMP) by the second generation Grubbs' catalyst. The results of gel permeation Chromatographic (GPC), thermogravimetric (TG), and differential scanning calorimeter (DSC) analyses of the obtained polymers will also be discussed.
