Process for preparing high bulk density vinyl resins |
摘要 |
Spherical particles of vinyl resins 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: <IMAGE> +TR <IMAGE> where n is from about 300 to about 1500.
