Abstract

Provided is a plurality of resin beads, wherein the resin beads comprise polymerized units of monovinyl aromatic monomer and polymerized units of multivinyl aromatic monomer, and wherein the 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, where the method comprises reacting the reactants with each other in the presence of such resin beads.

First claim

The invention claimed is:

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, wherein the chemical reaction is

wherein R 5 is either a hydrocarbyl group or a hydrocarbyl group attached to a carboxyl group that is capable of forming an anhydride group with the carboxyl group shown in structure I, and
wherein R 6 is an alkyl group.

2. 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.

3. The method of claim 2 , wherein said (meth)acrylic acid is methacrylic acid and wherein said alcohol is methanol.

4. The method of claim 1 , wherein R 6 is an alkyl group having 1 to 20 carbon atoms.

5. The method of claim 1 , wherein R 5 is a hydrocarbyl group having 1 to 20 carbon atoms.

6. The method of claim 5 , wherein R 6 is an alkyl group having 1 to 20 carbon atoms.

7. The method of claim 1 , wherein R 6 is an alkyl group having 1 to 4 carbon atoms.

8. The method of claim 1 , wherein R 5 is either a hydrocarbyl group with 8 to 20 carbon atoms or is a hydrocarbyl group of structure IV

wherein R 7 is hydrogen or an alkyl group.

9. The method of claim 8 , wherein R 6 is an alkyl group having 1 to 4 carbon atoms.
