Abstract

The present invention relates to a polymer comprising a repeating group having the structure of formula (I)

wherein R, R 1 , R 2 , R 3 , R 4 , X, and s are as described herein and salt thereof. Also disclosed is a process of synthesizing such polymers.

First claim

What is claimed:

1. A homopolymer having the structure of formula (I):

wherein

is a repeating group of the homopolymer;
X is NH or O;
R is independently selected from the group consisting of H and C 1-20 alkyl;
R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of H and

with the proviso that at least one of R 1 , R 2 , R 3 , or R 4 is not hydrogen;
U is optional and, if present, is —(S) p —;
*- is a point of attachment to formula (I) or R 1 , R 2 , R 3 , or R 4 ;

is a terminal group of the polymer;
k is 1 to 1,000,000;
p is 1 to 8;
z is 45.8 to 10,000,000; and
s is 1 to 50;
or a salt thereof.

2. The homopolymer according to claim 1 , wherein the repeating group has the structure of formula (Ia):

s is 1-50, and k is 1 to 1,000,000.

3. The homopolymer according to claim 1 , wherein z is from 51.4 to 10,000,000.

4. The homopolymer according to claim 1 , wherein z is from 66.7 to 10,000,000.

5. The homopolymer according to claim 1 , wherein z is from 175.6 to 10,000,000.

6. The homopolymer according to claim 1 , wherein z is from 179.3 to 10,000,000.

7. The homopolymer according to claim 1 , wherein z is from 183.8 to 10,000,000.

8. The homopolymer according to claim 1 , wherein z is from 785.2 to 10,000,000.

9. The homopolymer according to claim 1 , wherein z is from 1060.4 to 10,000,000.

10. The homopolymer according to claim 1 , wherein z is from 1558.8 to 10,000,000.
