Patent ID: 8546517

Claim:
A poly(bisoxalamide) comprising a plurality of repeat units of formula (I): wherein for each repeat unit: g independently is an integer of from 0 to 40 (when g is 0, —R G —O— is absent); R G independently is —(CH 2 ) m —, —(CHR 1 ) m —, where m is an integer of from 2 to 4 and R 1 is (C 1 -C 10 )hydrocarbyl; —[C(═O)—(CH 2 ) b ]— where b is an integer 3 or 5; or —[C(═O)-A-C(═O)—O-D]— where A is a residual of a dicarboxylic acid and D is a residual of a diol; Each of R E and R T is a diradical residual of an alpha-amino acid, beta-amino acid, gamma-amino acid, or alpha,omega-amino acid having from 5 to 40 carbon atoms; R D independently is a diradical residual of an alpha,omega-diamine of from 2 to 40 carbon atoms; Y is N(H); and n is an integer of 2 or higher, the integer n indicating a total number of the repeat units comprising the poly(bisoxalamide).
