titleOfInvention | How to produce polycarbonate |
abstract | In the melt polymerization reaction, a process of polymerizing an aromatic dihydroxy compound and diaryl carbonate in the presence of a polymerization catalyst to produce a by-product vapor stream containing the dihydroxy compound, diaryl carbonate and diaryl carbonate by-product, a low vapor pressure compound, In addition to the by-product vapor stream, a step of generating a modified by-product vapor stream, a step of introducing the modified by-product vapor stream into the separator, and a volatile diaryl carbonate by-product from the modified by-product vapor stream in the separator A method of producing polycarbonate comprising the steps of removing matter to form a treated by-product stream and returning the treated by-product stream to a polymerization reaction. Alternatively, the low vapor pressure compound can be added directly to the separation device. |
