Abstract :
[en] Blending two immiscible telechelic polymers capped with acid and tertiary amine functions, respectively, is also expected to promote coulombic interactions between the end-groups and to engage the individual chains in a kind of multiblock copolymer. This work deals with the feasibility of block 'copolymerizing' polystyrene and polybutadiene by means of ionic interactions between the chains extremities. Polystyrene and polybutadiene bearing the same carboxylic acid end-groups were blended and investigated by differential scanning calorimetry. It could be concluded that a proton transfer occurs from the carboxylic acid to the amino group, resulting in the formation of a carboxylate anion and an ammonium cation attached to the polystyrene and polybutadiene chains, respectively. Electrostatic interactions between these two ions can trigger the polymer compatibilization.
