ABSTRACT:
Optically active polycarbonate, polyester, and polyurethane polymers prepared from monomers containing optically pure spirobiindane moieties are disclosed. The chiral spirobiindane polymers are of high molecular weight and exhibit high optical rotations. In addition, the optically active polymers are useful in the fabrication of optoelectronics devices and as polarizing coatings or filters or as polarized lenses.
