Styryl-ended rod-like macromonomers consisting, of poly(n-hexyl isocyanate) (2) (VB-HIC-n, where n is a degee of polymerization varying from 9 to 75) with relatively narrow molecular weight distribution (M-w/M-n < 1.2) have successfully been prepared in CH2Cl2 at room temperature by living coordination polymerization of n-hexyl isocyanate (HIC) using 4-vinvibenzyloxy-dichloro(cyclopentadienyl)titanium(IV) (1) as an initiator. The radical co-polymerization behavior of the rod-like macromonorners with styrene has been studied and summarized as a function of degree of polymerization of HIC. The apparent co-polymerizabilities of the rod-like macromonomer seem to be almost equivalent to styrene, suggesting that the reactivity is mainly determined by the chemical reactivity of the ended double bond.
