Abstract
Copolymers or terpolymers of carbon dioxide and at least one epoxide are found to be useful in formulations for adhesive compositions. Polarity due to the carbonate group and non-polarity due to the alkylene groups in the resulting polyalkylene carbonates makes it possible to adhere a large number of different surfaces such as steel, aluminum, fluoropolymers, and polyesters to themselves or to each other.
