ABSTRACT:
Method for producing polymers comprises connecting polymeric molecules at least one of which contains tertiary amino groups chemically bound in the chain in the presence of materials such as elemental halogens, compounds of the elements of groups 3 through 8 of the Periodic Table containing one or more halogen atoms or halogen containing organic compounds. It is possible to connect chains of identical or different types and in this way increase the molecular weight, produce block copolymers, cure films and varnishes and perform vulcanization and the like at ambient temperature.
