Abstract
Process for producing polymers comprising connecting polymeric molecules which contain chemically bound tertiary amino groups in the chain by oxidizing the macromolecules to be connected with air or an oxidizing agent such as compounds containing a peroxidic bond, for example, inorganic and organic peroxides, or organic anhydrides. It is possible to connect chains of identical or different types and in this way increase the molecular weight, produce block copolymers, cure films of varnishes and perform vulcanization and the like at ambient temperature.
