Amine-terminated liquid polymers and process for preparation thereof

Amine-terminated liquid polymers are prepared by reacting a carboxyl-terminated, ester-terminated or acid chloride-terminated liquid polymer having a carbon-carbon backbone with at least one aliphatic, alicyclic, heterocyclic or aromatic amine containing at least two secondary or mixed primary/secondary amine groups, but no more than one primary amine group per molecule. The novel amine-terminated polymers are useful as elastic vulcanizates, polymeric cure agents, tougheners and flexibilizers for epoxy resins, in paints and coatings, in sealants and adhesives, and the like.
