Abstract

PURPOSE: To prepare the titled polymer in high productivity, shortening the charging time and heat-up time in the polymerization, by charging specific amounts of the monomer and water heated roughly at the polymeerization temperature, thereby attaining the desired polymerization temperature at the completion of the charging of both components in the polymerizer.
CONSTITUTION: In the suspension polymerization of vinyl chloride or a mixture of ethylenic unsaturated monomers composed mainly of vinyl chloride, the temperatures of the monomer and water are adjusted so as to give a mixture of the monomer and water having a temperature of (the polymerization temperature ± 10°C), ≥50% of the total charging amounts of both components are charged in the polymerizer at the same time so as to attain the desired polymerization temperature at the completion of the charging, and the mixture is polymerized without delay. It is preferable to charge the polymerizer with the whole amount of water dissolved with the whole amount of a suspending agent (e.g. partially saponified polyvinyl alcohol) and the whole amount of the monomer dissolved with the whole amount of a polymerization initiator (e.g. dibutoxyethyl peroxy dicarbonate) at the same time.
