Heterogeneous copper precatalyst for the oxidizing polymerization of 2,6-dimethylphenol and method for obtaining it

摘要

heterogeneous copper prekatalizator for oxidative polymerization 2,6 - dimetylofenolu containing medium type silica is silica gel modified successively: alkilolitem and bromkiem copper (h).process to obtain heterogeneous prekatalizatora copper for oxidative polymerization 2,6 - dimetylofenolu containing medium of the silica is first silica gel flooding solution alkilolitu in inertnym solvent and then the resulting product after separating, bathes in the alcohol solution of bromide, copper (ii)after which yields obtained prekatalizator and drought known methods.
