ABSTRACT:
A process is described for preparing vinyl chloride polymers. The polymerization is carried out in an apparatus the inside walls and internal fitments of which have been coated with a reaction product which forms on reacting certain silanes with inhibitors for free-radical polymerizations and which contain in the molecule at least one aromatic or at least one quinonoid ring and at least one hydrogen atom which is bonded to an oxygen, sulfur or nitrogen atom with subsequent reaction with water, drying and heat treatment.
The wall-deposit formation observed with the new process is markedly smaller, in particular after several polymerization batches, than in the case of known processes.
