Vinyl chloride latex with low energy consumption and method for preparing the same

摘要

Disclosed is a polyvinyl chloride resin latex which is prepared by polymerization using a decreased amount of polymerization water in an early polymerization stage and then additional polymerization water in a late polymerization stage, so that the polyvinyl chloride resin latex has an increased solid content and a decreased water content and thus finally remarkably reduces energy consumption in a spray drying process.

主权项

1. A method for preparing a vinyl chloride resin latex comprising:
(a) initiating polymerization of 100 parts by weight of a vinyl chloride monomer and 40 to 55 parts by weight of polymerization water; and (b) further adding 5 to 20 parts by weight of polymerization water in a late polymerization stage.
