Fluorocarbon End-functionalized Polymers from Poly(arylether) Dendritic Initiators

Fréchet‐type poly(arylether) first and second generation (G1 and G2 respectively) dendrons were prepared from 1‐(bromomethyl)‐3,5‐bis(trifluoromethyl)benzene. The latter and the brominated versions of the two dendrons were successfully employed in the copper mediated living radical polymerization (L...

Description
Summary:Fréchet‐type poly(arylether) first and second generation (G1 and G2 respectively) dendrons were prepared from 1‐(bromomethyl)‐3,5‐bis(trifluoromethyl)benzene. The latter and the brominated versions of the two dendrons were successfully employed in the copper mediated living radical polymerization (LRP) of styrene‐d8 giving polymers of predictable molecular weights and narrow polydispersities. Contact angle measurements and ion beam analysis were used to explore the adsorption of these materials to the air‐polymer surface in blended films with unfunctionalized hydrogenous polystyrene. Although contact angle analysis indicated only modest changes in the hydrophobicity and lipophobicity of the surface, ion beam analysis clearly showed the formation of an excess layer of dendron functionalized polymer at the exposed surface that increased with increasing fluorine content.
