PROCEDIMIENTO PARA LA OBTENCION DE POLIMEROS DE ACRILONI- TRILO-CLORURO DE VINILO QUIMICAMENTE UNITARIOS. |
摘要 |
<p>The invention relates to a process for the production of a chemically uniform acrylonitrile vinyl chloride copolymer in an aqueous emulsion in the presence of a redox catalyst and with a fluctuating concentration of at least one iron salt in the reaction medium wherein the polymerization reaction is carried out at a pH value of from 2 to 6 in the presence of a mixture of an iron salt and a complex former, the complex former having certain apparent stability constants of the iron-II-complex and of the iron-III-complex.</p> |
