The monomers with <i>n</i>-hexyl, cyclohexyl, benzyl, and cholesteryl group as an ester group were transformed into the corresponding poly(alkoxycarbonylmethylene)s with <i>M</i><sub>n</sub> > 10 000. On the other hand, the polymerization of 1-adamantyl diazoacetate afforded low-<i>M</i><sub>n</sub> polymers (<i>M</i><sub>n</sub> < 4000), probably because of steric reasons. Copolymerization of a few comonomer combinations also proceeded successfully to give copolymers with <i>M</i><sub>n</sub> > 20 000.
