Abstract

Provided is a resin bead comprising functional groups of structure (S1).

First claim

The invention claimed is:

1. A resin bead comprising functional groups of structure (S1)

wherein —X— is a bivalent linking group, wherein —Y is a monovalent group having structure (S2)

wherein the circular structure in structure (S2) has four or more atoms,
wherein the mole ratio of multivalent atomiccations to —X— groups is either 0:1 or is 0.01:1 or lower.

2. The resin bead of claim 1 , wherein —Y is selected from the group consisting of structures (S3), (S4), and (S5):

wherein each of -A 1 -, -A 2 -, -A 3 -, -A 4 -, and -A 5 - is independently selected from the group consisting of structure (S6), (S7), and (S8):

wherein each of R 1 , R 2 , and R 3 is independently selected from the group consisting of hydrogen, hydroxyl, amine, unsubstituted alkyl, and substituted alkyl.

3. The resin bead of claim 1 , wherein —X— comprises one or more structure (S7), one or more structure (S8), one or more structure (S9), or a combination thereof, wherein structure (S7), structure (S8), and structure (S9) are defined as follows:

wherein the aromatic ring in structure (S9) may be substituted or un-substituted, and wherein each of R 1 and R 2 is independently selected from the group consisting of hydrogen, hydroxyl, amine, unsubstituted alkyl, and substituted alkyl, and
wherein R 3 is selected from the group consisting of hydrogen, unsubstituted alkyl, and substituted alkyl.

4. The resin bead of claim 1 , wherein the mole ratio of —Y groups to —X— groups is 0.99:1 or higher.

5. A collection of the resin beads of claim 1 , wherein the collection has harmonic mean diameter of 200 μm or higher.

6. The collection of resin beads of claim 5 , wherein the collection has uniformity coefficient of 1.02 or greater.
