Detecting the endpoint in interfacial aromatic poly-carbonate polymerization reactions. |
摘要 |
<p>A method is provided for detecting the endpoint of an interfacial aromatic polycarbonate polymerization reaction. The method involves illuminating a sample of the polymerization reaction mixture with a light source and monitoring the extent of apparent light scattering of the sample throughout the course of the polycondensation reaction until at the endpoint, a predetermined threshold extent of apparent light scattering is achieved.</p> |
