| titleOfInvention | Filter alignment during polycarbonate production |
| abstract | In one embodiment, polycarbonate polymerization method includes: in the presence of interfacial catalysis agent, make carbonate products and dihydroxy compounds interfacial polymerization, to form polycarbonate, and be added to thinner and ester exchange catalyst in the polycarbonate of first filter upstream, to form the polycarbonate of adjustment.It can be introduced into replacement filter with replacement filter replacement first filter and by the polycarbonate of adjustment.Flowing can be diverted to replacement filter.This method further comprises reducing the adding rate of thinner and ester exchange catalyst, until adding rate is 0mol/ hours. |
