<p>A polycarbonate comprises
repeating units respectively represented by formulas (1) and (2):
(wherein R 1 to R 6 represent a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, or an aryl group: "R 1 and R 2 ", "R 3 and R 4 ", and "R 5 and R 6 " may be bonded to each other to form rings, respectively; R 7 and R 8 represent an alkyl group, an alkenyl group, or an aryl group; and m and n represent an integer of 0 to 4), wherein
the repeating units are placed at random,
relative to 100 mol% of all the repeating units, a content of the repeating unit represented by the formula (1) is 55 mol% to 98 mol% inclusive, and a content of the repeating unit represented by the formula (2) is 2 mol% to 45 mol% inclusive, and
the polycarbonate has a glass transition temperature of 160°C or higher.</p> |
