| abstract |
1. A METHOD OF PREPARING SOLID INERT BEADS COMPRISING A FULLY POLYMERIZED UREA OF PHENOL-FORMALDEHYDE RESIN COMPRISING THE STEPS OF: (A) REACTING A UREA OR A PHENOL AND A FORMALDEHYDE, WHEREIN THE MOLAR RATIO OF THE UREA TO THE FORMALDEHYDE IS FROM ABOUT 1:1 TO ABOUT 3:0.5 AND WHEREIN THE MOLAR RATIO OF THE PHENOL TO THE FORMALDEHYDE IS FROM ABOUT 1:1 TO ABOUT 1:3, IN A BASIC AQUEOUS MEDIUM TO FORM A PREPOLYMER; (B) BLENDING SAID PREPOLYMER WITH A HYDROXYFUNCTIONAL PROTECTIVE COLLOID-FORMING MATERIAL; (C) POLYMERIZING THE PREPOLYMER BY ACIDIFYING THE MIXTURE THUS FORMED UNDER AGITATION, THEREBY FORMING PARTICULATE BEADS AND AGGLOMERATING SAID BEADS TO A GROSS PARTICLE SIZE OF FROM ABOUT 1 MICRON TO ABOUT 50 MICRONS; AND (D) COLLECTING SAID UREA OR PHENOL-FOMALDEHYDE PARTICULATE BEADS. |
