Bioadvantaged nylon: polycondensation of 3-hexenedioic acid with hexamethylenediamine
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.
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.
