PURPOSE:To obtain plastic film or sheet having excellent weather resistance by adding a copolycarbonate resin having UV absorbing power containing specifically structured copolycarbonate resin and/or specific terminal group to a thermoplastic resin so as to mold by extrusion molding. CONSTITUTION:A copolycarbonate resin shown in the formulas I and II and having 0.1-70mol% in the structural unit II and/or a copolycarbonate resin having UV absorbing power containing a terminal group shown in the formula III is added and mixed to a thermoplastic resin of 0.1-10pts.wt. so as to mold by extrusion molding. In the formula I, A expresses direct bonding, alkylidene group and others. In the formula II, B expresses 1-10C alkylidene group and others, R<1>-R<8> express hydrogen atom and others. Also, in the formula III, p is an integer of 1-10, q is 1 or 2, R<12>-R<14> express halogen atom and others. Thus, a plastic sheet or film, with which deterioration of working environment due to volatilization of a UV absorbent and stain of a calender roll do not occur, can be obtained. |
