PREPARATION OF PHENOL-FORMALDEHYDE RESIN BEADS USING SUSPENSION OR EMULSION POLYMERIZATION |
摘要 |
Methods for making polymer particles in gel form via an emulsion and/or suspension polymerization are provided. In at least one specific embodiment, the method can include reacting a first reaction mixture comprising a phenolic monomer, an aldehyde monomer, and a first catalyst to produce a prepolymer. The method can also include combining the prepolymer with a carrier fluid and a second catalyst to produce a second reaction mixture. The second catalyst can include a dicarboxylic acid, an anhydride, a dihydroxybenzene, or any mixture thereof. The method can also include polymerizing the prepolymer to form polymer particles in gel form. |
