Abstract
A wide range of fluorinated norbornenes and norbornadienes are subjected to ROMP using well-defined Schrock initiator based on Mo(CH-t-Bu)(NAr)(O-t-Bu)2. All of the polymerisations show characteristics of well-ordered living systems; e.g. (a) the persistence of propagating alkylidenes in the polymerisation mixtures as observed by 1H nmr spectroscopy, (b) narrow molecular weight distributions of the resultants polymers and (c) the synthesis of diblock copolymers.
Diblock fluorinated copolymers incorporating segments of the homopolymers of a wide range of fluorinated norbornenes and norbornadienes monomers are synthesised by sequential addition. The block copolymers also show narrow molecular weight distribution.
The fluorinated homopolymers and block copolymers described here are characterised using 13C. 19F, and 1H nmr spectroscopy, differential scanning calorimetry and gel permeation chromatography.
