Abstract

Polystyrene macromonomers, fitted with a norbornenyl unsaturation in α position, have been obtained from a norbornene based carbanionic initiator that has been purposely designed to this end. The advantages of this synthetic scheme over that based on the deactivation of living PS chains are emphasized. One of the macromonomers prepared has been subsequently polymerized by ring‐opening metathesis, using a Schrock complex as initiator. The characterization of the resulting polymacromonomers showed that the metathesis process occurred under “living” conditions.

Norbornene-ended polybutadiene (PBu) macromonomers have been prepared via two different routes: a-norbornenyl-polybutadiene was derived from a norbornene-containing carbanionic initiator, whereas w-norbornenyl samples were obtained through deactivation of living polybutadienyl anions by a norbornene

## Abstract Poly(oxy‐2,6‐dimethyl‐1,4‐phenylene) samples with bicyclic olefin end groups were obtained by esterification of the hydroxyl end group of the poly(phenylene oxide) with bicyclo[2.2.1]hept‐5‐ene‐2‐carbonyl chloride. Mixtures of these macromonomers with bicyclo[2.2.1]hept‐5‐ene‐2‐carboxyl
