TECHNOLOGY FOCUS - POLYMERS - Preparation (claimed): The polycarbonate resin is prepared using binaphthalene derivative of formula (II) as a raw material. Preferred Properties: The polycarbonate resin has refractive index of 1.640-1.680, Abbe's number of 24 or less, orientation birefringence of 1x 10-3 or less. 5 wt.% Loss temperature of the polycarbonate resin measured in temperature increase rate of 10 degrees C/minute is 350 degrees C or more. Preferred Process: The binaphthalene derivative (II) is reacted with 4-(9-(4-hydroxyphenyl)-9H-fluoren-9-yl)phenol of formula (V) or 2-(4-(9-(4-(2-hydroxyethoxy)phenyl)-9H-fluoren-9-yl)phenoxy)ethan-1-ol of formula (VI), and distilling to remove monohydroxy compound, to obtain polycarbonate resin. Preferred Composition: The polycarbonate resin further has fluorene-type structural unit (B) of formula (III) and structural unit (C) of formula (IV). The molar ratio of the structural unit (A) and structural unit (B) is 20/80-99/1. The structural unit (A) is preferably of formula (A1). The structural unit (B) is preferably of formula (B1) or (B2). The content of the structural unit (A) is 1-99 mol%, with respect to total content of the structural units in the resin.R1,R2=H, 1-20C alkyl, 1-20C alkoxy, 5-20C cycloalkyl, 5-20C cycloalkoxy, 6-20C aryl or 6-20C aryloxy. EXAMPLE - 13.4 g 2,2'-Bis(2-hydroxyethoxy)-1,1'-binaphthalene, 35.6 g 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene, 25 g diphenyl carbonate and 8.8x 10-5 g sodium hydrogen carbonate were added into a reactor, heated at 180 degrees C for 110 minutes under nitrogen atmosphere and reacted for 20 minutes. The pressure inside the reactor was adjusted to 200 mmHg, heated at 230 degrees C for 1-10 hours in a rate of 75 degrees C/hour, the temperature of the reactor was increased at 240 degrees C for 30 minutes in rate of 60 degrees C/hour. Nitrogen was introduced into the reactor after completion of reaction and pressure inside the reactor was adjusted to normal pressure, to obtain polycarbonate resin.
