Beschreibung
Zusammenfassung:	A cationic polymerization process for the synthesis of nano-structured polymers containing graphene which comprises reacting graphite oxide dispersed in a solvent by means of ultrasounds, with at least one vinyl monomer and at least one vinyl aromatic monomer, in the presence of at least one strong inorganic acid and suitable for activating a cationic polymerization, wherein: - said graphite oxide contains from 5% to 60% by weight of bound oxygen, - said vinyl monomer contains at least one carboxylic group wherein the ratio between oxygen bound to the oxide and carboxylic groups ranges from 1: 10 to 10: 1 in moles per mole, and--the ratio between said vinyl aromatic monomer and the sum of the quantity of graphite oxide and vinyl monomer containing carboxylic groups ranges from 50% to 99% by weight.
