[EN] Polyfunctional cyclic carbonates provide a useful additional monomer for energy-initiated cationic copolymerisation with such other monomers and oligomers as epoxides and oxetanes. [FR] L'invention concerne des carbonates cycliques polyfonctionnels constituant un monomère supplémentaire utile pour la copolymérisation cationique amorcée par l'exposition à une énergie avec d'autres monomères et oligomères tels que des époxydes et des oxétanes.
The field of the invention relates to a novel family of polycyclic carbonates made of mixed cyclic and linear carbonates functions showing a surprising anisotropic behaviour in their electrically conductive properties. Films of those polycyclic carbonates show an electric conductive behaviour perpendicular to the conductor or semiconductor treated surface and an electrical resistance typical to polymers in the direction of the film formed on the surface. This surprising behaviour is useful for the performance improvement and modification of electron transfer devices and elements, such as batteries, all electronic devices and components, visual displays, memories, quantum dots, electrodes and solar energy converting elements to name some.
