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.

Preparation of phenol-formaldehyde resin beads using suspension or emulsion polymerization

An anhydride and resorcinol latent catalyst system for a phenolic resole resin provides a resin having long pot life and long shelf life, yet cures quickly thereafter.

Anhydride and resorcinol latent catalyst system for improving cure characteristics of phenolic resins

This invention relates to a resin composition capable of being thermally cured while minimizing or eliminating voids in the resulting composite, the composition having both a long pot life at low temperatures and a fast curing rate at higher temperatures containing a mixture of (a) a phenol-formaldehyde resole resin, and (b) an etherified hardener, the etherified hardener being prepared from an alkoxylated polyol or a mono epoxy functional diluent.

Phenolic resin compositions containing etherified hardeners

This invention relates to a resin composition capable of being thermally cured having both a long pot life at low temperatures and a fast curing rate at higher temperatures containing a mixture of (a) a phenol-formaldehyde resole resin, and (b) a latent curing agent selected from a particular class of nitrogen-containing acidic phosphorus compounds made from either phosphoric acid or phosphorous acid.
