Recent Developments in the Synthesis of Fluorinated Homopolymers and Block Copolymers via Living Rines 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 .C. .F, and .H nmr spectroscopy, differential scanning calorimetry and gel permeation chromatography.
