Polymerisation processes and products |
摘要 |
Beads are made from water-soluble monomer or monomer blend by reverse phase bead polymerization by extruding aqueous monomer beads into or onto the top of an upflowing column of non-aqueous liquid and the beads polymerise as they float downwardly through the column during a period of at least ½ minute. The resultant beads can have a very narrow particle size distribution. |
