Silane-type coupling agent, process for its preparation, and its use for the production of a conducting coating on glass
The coupling agent is comprised of a pyrrolidyl group capable of being incorporated in the chain of an electroconducting polymer, and a silane group --Si(OR.sup.1).sub.3 which may be chemically bound to a glass substrate in order to form an adherent coating of said polymer. It is obtained by an addition reaction implementing an epoxide function and a primary or secondary amine function.
