摘要:
The present invention relates to an agitator for suspension polymerization having a more improved structure in effect in contrast to the earlier agitator. The present invention also relates to an improved suspension polymerization method of vinyl chloride using a polymerization reactor equipped with that agitator, by which vinyl chloride resin having excellent quality can be prepared with a diminution of the number of fish eyes which cause many problems such as deterioration of the processed article, low productivity, etc.
摘要:
The present invention relates to a build-up suppressant used for suppressing the formation of a build-up during the polymerization reaction and to a process for the preparation thereof. The present invention also relates to a method for suppressing the build-up formation by forming a coating film on the reactor internal surface with the build-up suppressant and to a method for polymerization of vinyl halide or vinyl monomers having aromatic group(s) in the above reactor internally coated.
