Abstract

Official abstract text for this publication.

A method of making a plurality of resin beads comprising (a) providing a reaction mixture comprising monovinyl aromatic monomer, multivinyl aromatic monomer, and porogen, (b) performing aqueous suspension polymerization on said reaction mixture to form resin beads, and (c) sulfonating said resin beads. Also provided is a plurality of resin beads, wherein said resin beads comprise polymerized units of monovinyl aromatic monomer and polymerized units of multivinyl aromatic monomer, wherein said resin beads have BET surface area of 15 to 38 m2/g and volume capacity of 0.7 or higher. Also provided is a method of making a product of the chemical reaction of one or more reactants, said method comprising reacting said one or more reactants with each other in the presence of the plurality of such resin beads.

First claim

Opening claim text (preview).

The invention claimed is: 1. A plurality of sulfonated resin beads, wherein said resin beads comprise (i) 93.5% to 96% polymerized units of monovinyl aromatic monomer, by weight based on the weight of said resin beads, (ii) 4% to 6.5% polymerized units of multivinyl aromatic monomer, by weight based on the weight of said resin beads, wherein said resin beads have BET surface area of 15 to 38 m 2 /g and volume capacity of 0.7 or higher. 2. The plurality of resin beads of claim 1 , wherein said resin beads have pore volume of 0.1 to 0.29 cm 3 /g. 3. The plurality of resin beads of claim 1 , wherein the resin beads comprise no polymerized units of any monomer other than the one or more monovinyl aromatic monomer and the one or more multivinyl aromatic monomer. 4. The plurality of resin beads of claim 1 , wherein the quotient formed by dividing the number of moles of sulfonate groups by the number of moles of aromatic rings in the polymerized units of the resin beads is 0.8 or higher.
