Abstract
There are disclosed carbonate polymers of dihydroxyaryl fluorene having crosslinkable moieties. There are also disclosed such polymers in the form of composites. The polymers of this invention are capable of being crosslinked by activation of the crosslinkable moieties. Once crosslinked, these polymers demonstrate an excellent combination of properties including resistance to melting at high temperatures, solvent resistance, optical clarity, impact resistance, and physical strength.
Claims19
A carbonate polymer comprising in polymerized form a dihydroxyaryl fluorene multihydric monomer and optionally up to about 99 mole percent of a second multihydric monomer which is not a dihydroxyaryl fluorene, which mole percent is based on the total moles of multihydric monomer, and a crosslinkable moiety wherein the mole ratio of crosslinkable moiety to multihydric monomer is at least about 0.001 to 1 and up to about 5 to 1.
