Branched polycarbonate and method |
| abstract |
The present invention discloses a vapor phase method of introducing a branching agent such as THPE into a solid polycarbonate while simultaneously crystallizing the solid polycarbonate. The partially crystalline polycarbonate containing a branching agent introduced in this manner is suitable for use in the preparation of branched polycarbonates by solid state polymerization. Branching in the polycarbonates so produced is demonstrated by rheometric measurements. Such branched polycarbonates are known to possess increased material melt strength, shear sensitivity, and complex viscosity ratio, and are particularly well-suited in blow molding applications. |
