There are two processes to polymerize polycarbonate in the petrochemical industry: One is interfacial polymerization and the other is melt polymerization(melt PC). Recently, the latter is mostly used in that it is eco-friendly process. The most difference of product produced by two systems is the content of specific end-group. It detects a little bit value in interfacial polymerization, while it generally has more content in melt polymerization. It is supposed that the more content of the end-group is, the bigger change of the property induce as surrounding environment. In order to analyze an effect of the end-group, polycarbonate substituted to other end-group was made from melt PC using a suitable end-capping agent. And then, several properties were examined like melt index and color. As the result, the end-capped PC showed less change of the properties than general melt PC. It was verified that the properties of melt PC is adversely affected by the specific end-group. |
