NOVELTY - Polycarbonate composition comprises polycarbonate (PPCP) and polypropylene (PPC), where the mass ratio of PPCP/PPC is (1-99):(99-1). USE - Polycarbonate composition used in plastic. ADVANTAGE - The polycarbonate composition has excellent mechanical property and degradability, and improved barrier property and thermal stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a plastic containing polycarbonate composition, which comprises a 90-120 pts. wt. polycarbonate composition, 1-3 pts. wt. ester compound, 0.2-0.6 pts. wt. block oligomer, 5-15 pts. wt. of pigment filler, 0.1-0.3 pts. wt. of antistatic agent, 0.5-2 pts. wt. of isocyanate compound; 2. method for preparing plastic containing polycarbonate composition, which involves: a. pre-mixing PPCP and PPC, then adding other raw materials to mix uniformly, b. putting the mixture into a double-screw extruder extruding and granulating to obtain the product
