Polyisocyanates containing side functional groups were synthesized by anionic polymerization. Furfuryl isocyanate (FIC) was polymerized using sodium benzanilide (Na-BA) initiator in tetrahydrofuran at -98 �C. To confirm the living natures of polymerization, we carried out polymerization changing mole ratio between monomer and initiator, and reaction time, and also carried out block copolymerization with n-hexyl isocyanate (HIC). The results indicated that PFIC was successfully synthesized in quantitative yield, and controlled molecular weight (MW) and narrow molecular weight distribution (MWD). PFIC was well reacted with maleimide and C60 by Diels-Alder reaction. Anionic polymerization of 3-chloropropyl isocyanate (3-CPIC) was also carried out changing reaction time. However, the polymer with low yield, uncontrolled MW and MWD was obtained and trimerization couldn't be prevented. In order to get more controlled polymer, P2VP-b-P3CPIC was synthesized. PS-g-(P2VP-b-P3CPIC) graft copolymer also was synthesized by highly reactive nature of chlorine atom.
