Method of making ligand functionalized substrates
Ligand functionalized substrates, methods of making ligand functionalized substrates, and methods of using functionalized substrates are disclosed.
1. A monomer having a (meth)acryloyl group, wherein the monomer has formula:
wherein
R 1 is H or C 1 -C 4 alkyl, R 7 and R 8 are each independently C 1 to C 10 alkylene; and
Z is an ester, amide, urethane or urea linking group,
the monomer being a reaction product of
a) a first compound that is a
1) an alkenyl oxazolinone; or
2) a (meth)acryloyl monomer having an isocyanato group; and
b) a second compound of the formula
wherein
R 2 is a divalent alkylene and optionally further contains a second group that is an ester, amide, urethane or urea linking group;
each R 3 is independently H or C 1 -C 4 alkyl;
R 4 is H, C 1 -C 4 alkyl or —N(R 3 ) 2 ; and
X 1 is —O— or —NR 3 —.
2. The monomer of claim 1 , wherein Z is a urea linking group.
3. The monomer of claim 1 , wherein Z is an amide linking group.
4. The monomer of claim 1 , wherein the (meth)acryloyl monomer having the isocyanato group is isocyanatoethyl methacrylate.
5. The monomer of claim 4 , wherein the monomer is
