CpTiCl{sub 2}(OMMA), 1, [-OMMA = alkoxide of methyl {alpha}-(hydroxymethyl)acrylate] was synthesized from CpTiCl{sub 3} and methyl {alpha}-(hydroxymethyl)acrylate and used in the synthesis of a poly(n-hexyl isocynate) segments attached to a poly(methyl methacrylate) backbone. Methyl methacrylate and 1 were copolymerized (5% titanium containing monomer feed) using AIBN initiator at 80{degrees}C to yield a copolymer with pendant titanium alkoxide groups. Treatment of this copolymer with n-hexyl isocyanate produced the title comb polymer.
