Abstract
Official abstract text for this publication.
The present invention relates to a method of preparing a vinyl chloride polymer, and more precisely, a method of preparing a vinyl chloride polymer having excellent processability by raising a final polymerization temperature up to 5˜20° C. from an first polymerization temperature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of preparing a vinyl chloride homopolymer comprising: polymerizing vinyl chloride monomer in the presence of a solvent, a polymerization initiator, a protective colloid auxiliary, and a pH regulator at a polymerization temperature of 30° C. to 75° C., wherein 120 to 150 weight part of the solvent, 0.02 to 0.2 weight part of the polymerization initiator, 0.03 to 5 weight part of the protective colloid auxiliary and 0.01 to 1.5 weight part of…
