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 m 2 /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).
1 . 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 a plurality of 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 method of claim 1 , wherein said product comprises an ester, and wherein said reactants comprise a carboxylic acid and an alcohol. 3 . The method of claim 1 , wherein said product comprises a (meth)acrylate ester, and wherein said reactants comprise (meth)acrylic acid and a C 1 to C 3 alcohol. 4 . The method of claim 3 , wherein said (meth)acrylic acid is methacrylic acid and wherein said alcohol is methanol.
