Abstract
Un método para polimerizar cloruro de vinilo con el fin de impedir que se depositen incrustaciones de polímeros sobre las paredes y otras superficies en contacto con monómeros en un reactor de polimerización. De acuerdo con el método, uno o varios productos, entre yodo, compuestos de yodo, bromo, compuestos de bromo, tiocianato, isotiocianato, ácido fítico, sus derivados, hidratos de carbono reductores y ciertos otros compuestos se anaden a la mezcla de polimerización. El efecto de este método puede fomentarse sinérgicamente con revestimientos de un compuesto orgánico o un tinte orgánico polar o un tinte orgánico sobre aquellas superficies.A method of polymerizing vinyl chloride to prevent polymer scale from depositing on walls and other surfaces in contact with monomers in a polymerization reactor. According to the method, one or more products, including iodine, iodine compounds, bromine, bromine compounds, thiocyanate, isothiocyanate, phytic acid, its derivatives, reducing carbohydrates and certain other compounds are added to the polymerization mixture. The effect of this method can be synergistically promoted with coatings of an organic compound or a polar organic stain or an organic stain on those surfaces.
