Classification: CPC B  C | IPC B  C

Claim 11:
12. A method of forming a thiol-functionalized crosslinked vinylbenzylchloride-divinylbenzene copolymer, the method comprising:
copolymerizing vinylbenzylchloride monomers and divinylbenzene monomers into a vinylbenzylchloride-divinylbenzene copolymer in the presence of a porogenic solvent;
crosslinking the vinylbenzylchloride-divinylbenzene copolymer;
chloromethylating the vinylbenzylchloride-divinylbenzene copolymer to form a chloromethylated vinylbenzylchloride-divinylbenzene copolymer; and
thiolating the chloromethylated vinylbenzylchloride-divinylbenzene copolymer using a thiourea to form the thiol-functionalized crosslinked vinylbenzylchloride-divinylbenzene copolymer.
