Abstract
Linear polymers and copolymers having tunable coefficients of thermal expansion can be derived from dibenzocyclooctene-based monomers. The dibenzocyclooctene-based monomer can comprise a dibenzocyclooctene or a heterocyclic derivative of dibenzocyclooctene. For example, the linear polymer can comprise a polymer or copolymer of a dibenzocyclooctene-based moiety and a polyester, polyamide, polyimide, polyurethane, or epoxy.
Claims10
A linear polymer comprising a dibenzocyclooctene-based moiety having a tunable coefficient of thermal expansion.
A method of synthesizing a linear polymer having a tunable coefficient of thermal expansion, comprising:
- providing a dibenzocyclooctene-based monomer having functionality on each of the aromatic rings;
- and
- reacting the dibenzocyclooctene-based monomer with at least one other monomer to provide a linear polymer or copolymer having dibenzocyclooctene-based moieties.
A method of synthesizing a linear polymer comprising having a tunable coefficient of thermal expansion, comprising:
- providing a Tröger's base precursor polymer;
- and
- reacting the precursor polymer with methyl iodide followed by alkaline hydrolysis, whereby the bicyclic amine of the Tröger's base undergoes a ring opening, thereby providing a copolymer comprising a Tröger's base and a benzodiazacyclooctene.
