PROCESS FOR PREPARING HIGH BULK DENSITY RESINS

摘要

Spherical particles of vinyl resin having high bulk density can be prepared by the suspension polymerization process by using as a dispersant an alkyl hydroxy cellulose having a viscosity of from about 1000 to about 100,000 cps. A suitable dispersant is a hydroxypropyl methyl cellulose polymer having the formula: where n is from about 300 to about 1500.
