Abstract

A polymer is disclosed, which includes a structure of Formula 1 or Formula 2.

R 1 is a C 2-18 alkylene group or a C 6-18 arylene group, R 2 is a C 1-18 alkyl group, and R 3 is a functional group of Formula 3.

Each of X 1 , X 2 , X 3 , X 4 , X 5 , and X 6 , being the same or different, is H or methyl. Each of p, q, and r, being the same or different, is an integer of 1 to 60. R 4 is —C 2 H 4 —, —C 3 H 6 —,

Each of m and n, being the same or different, is an integer of 0 to 50, and m+n≠0.

First claim

What is claimed is:

1. A polymer consisting of a structure of Formula 1 or Formula 2:

wherein R 1 is a C 2-18 alkylene group or a C 6-18 arylene group,
R 2 is a C 1-18 alkyl group, and
R 3 is a functional group of Formula 3:

each of X 1 , X 2 , X 3 , X 4 , X 5 , and X 6 , being the same or different, is H or methyl;
each of p, q, and r, being the same or different, is an integer of 1 to 60;
R 4 is —C 2 H 4 —, —C 3 H 6 —,

each of m and n, being the same or different, is an integer of 0 to 50, and
m+n≠0.

2. The polymer as claimed in claim 1 , wherein:
R 1 is hexylene group;
R 2 is octyl group;
X 1 is CH 3 , X 2 is H, X 3 is CH 3 , X 4 is H, X 5 is H, and X 6 is H;
p=1, q=3, and r=19.

3. The polymer as claimed in claim 1 , wherein:
R 1 is hexylene group;
R 2 is octyl group;
X 1 is CH 3 , X 2 is H, X 3 is CH 3 , X 4 is H, X 5 is H, and X 6 is H;
p=1, q=2, and r=42.

4. The polymer as claimed in claim 1 , wherein:
R 1 is hexylene group;
R 2 is octyl group;
X 1 is CH 3 , X 2 is H, X 3 is CH 3 , X 4 is H, X 5 is H, and X 6 is H;
p=1, q=8, and r=58.

5. The polymer as claimed in claim 1 , serving as a dispersant of a powder.

6. A dispersion, comprising:
100 parts by weight of powder;
1 to 80 parts by weight of a dispersant, wherein the dispersant is the polymer as claimed in claim 1 ; and
100 to 900 parts by weight of solvent.

7. The dispersion as claimed in claim 6 , wherein the powder comprises metal, metal oxide, inorganic pigment, or organic pigment.

8. The dispersion as claimed in claim 6 , wherein the solvent comprises water, diethylene glycol diethyl ether, diethylene glycol dimethyl ether, propylene glycol monomethyl ether acetate, diethylene glycol butyl ether acetate, ethylene butyl ether, tetraethylene glycol dimethyl ether, or a combination thereof.

9. The dispersion as claimed in claim 6 , wherein the powder has a diameter of 20 nm to 10 μm.
