Patent ID: 8241461

Claim:
A polymer of Formula I: wherein A is Cl, Br, OH, NO 3 , or BF 4 ; each W independently is (CH 2 ) 1-8 or each Y independently is (CH 2 ) 1-8 or each R 1 independently is H, and each R 2 is H; or R 1 and R 2 together with the nitrogen to which they are attached form with the proviso that about 20 mole percent to about 40 mole percent of R 1 are H; each R 3 independently is H or OH; p is 1-8; each q independently is 0-8; wherein the molar ratio of W to Y is about 0.8:1 to about 1.4:1; and, wherein Formula I has a biobased content of at least about 95%.
