Continuous process for the preparation of copolycarbonate resins |
| abstract |
A continuous process for the preparation of copolycarbonate resins has great advantages in preparing molding materials of intricate structure or of thin-wall: the molding process may be conducted easily at a relatively low temperature; the copolycarbonate has excellent impact strength especially at a low temperature; and they have excellent melt flow, i.e. 2 to 3 times of the conventional polycarbonates. The present invention is a new polycondensation process which is carried out sequentially by using serially connected tube-type reactors to simplify the process; and enhancing the rate of reaction for an incorporation of comonomer into the polymer backbone resulting from varying Reynols Number, Linear Viscosity and Weber Number. |
