| titleOfInvention | A kind of lampshade Polycarbonate Production Process |
| abstract | The present invention relates to a kind of lampshade Polycarbonate Production Process, comprise the following steps：Using phenol as raw material, diphenyl carbonate is prepared through interface phosgenation reaction；Diphenyl carbonate carries out ester exchange reaction with bisphenol-A in the presence of a catalyst and obtains oligomer, mainly generates the oligomer that the degree of polymerization is 36；The oligomer that further ester exchange is formed, which reacts, generates the makrolon of more high polymerization degree.The advantage of the invention is that：Raw material is simple, and reaction is less demanding, without using solvent, avoids numerous and diverse subsequent treatment process. |
