A melt-polymerized polycarbonate is disclosed. The polycarbonate has a shear thinning ratio (y) that is defined by the limiting values of the following equationwherein y>=1, c=0.3 to 0.1, b=14.831±0.05 to 0.02, a=0.1262±0.005 to 0.003 and x is the relative viscosity of the polycarbonate. The polycarbonate exhibits a flow behavior similar to that of a linear polycarbonate of comparable molecular weight obtained by the interface polymerization process. |
