  • TREATING VINYL AROMATIC RESIN
    Publication number: 20190291096
    Abstract: Provided is a method of treating a vinyl aromatic resin (I) comprising (a) bringing the vinyl aromatic resin (I) into contact with an alcohol, and maintaining the contact between the vinyl aromatic resin (I) and the alcohol for 10 minutes or more, and (b) bringing the vinyl aromatic resin into contact with a base. wherein the vinyl aromatic resin (I), prior to steps (a) and (b), has benzyl chloride groups, benzyl alcohol groups, and methylene bridge groups.

  • PROCESS FOR MAKING UNIFORM POLYMER BEADS
    Publication number: 20110160328
    Abstract: A process for making substantially uniform polymer particles in an aqueous dispersion comprising forming a monomer emulsion with an emulsifying agent, at least one monomer molecule, and an initiator; adding the monomer emulsion to at least a stabilizing agent and a plurality of oligomeric droplets; and polymerizing the at least one monomer molecule to form an aqueous dispersion of polymer particles.

  • Swellable particles
    Publication number: 20070066761
    Abstract: There is provided a method for making swellable particles, said method comprising mixing initial particles, at least one monomer, at least one initiator, and at least one chain-transfer agent, wherein said mixing is performed under conditions in which said monomer is capable of forming oligomer or polymer or a mixture thereof. Also provided are swellable particles made by that method. Further provided is a method of making polymeric resin particles comprising mixing at least one subsequent monomer to those swellable particles and polymerizing said subsequent monomer.
