1. A method for making polymer particles in gel form via an emulsion or suspension process, the method comprising preparing a reactant mixture comprising a monomer component containing one or more phenolic compounds and one or more crosslinking compounds, and a carrier fluid, wherein:

  • the carrier fluid contains less than 50 wt % cyclohexane, based on the total weight of the carrier fluid,the monomer component polymerizes to form the polymer particles in gel form,the carrier fluid comprises an acid, a base, a catalyst, or a combination thereof, at a concentration for each species of at least 50% of the saturation limit, anda volume average particle size (Dv,50) of the polymer particles in gel form is greater than or equal to 1 mm.
