    摘要： The birefringent film of the present invention contains an aromatic polyester having a repeating unit represented by the following general formula (1).In the general formula (1), A(s), B(s), C(s), and D(s) are each independently represent a group selected from a halogeno group, an alkyl group which has 1 to 6 carbon atoms, and an aryl group. Also, a and b each represent an integer of 0 to 4, and c and d each represent an integer of 0 to 3. R1 represents a hydrogen atom, or an alkyl group which has 1 to 10 carbon atoms. R2 represents an alkyl group which has 2 to 10 carbon atoms. R3 to R6 each independently represent a group or atom selected from a hydrogen atom, a halogeno group, an alkyl group which has 1 to 6 carbon atoms, and an aryl group. Furthermore, l and m each represent an integer of 2 or more.

    摘要： Novel copolymers are prepared by the interaction of low or high molecular weight polyarylates, such as bisphenol A-isophthalate-terephthalate polyarylates, or bisphenol A-isophthalate-terephthalate-carbonate polyarylates and a high molecular weight diprimary dialcohol polyester polymer, such as polyethylene terephthalate polymer. The resulting copolymers are transparent and tough. They maintain their dimensional stability over a wide range of temperature from 75.degree.-175.degree. C., are soluble in chlorinated solvents, and have one glass transition point.
