Patent ID: 8765164

Claim:
A crystalline or semi-crystalline poly(ester urea) (PEU) polymer composition having formula (II): wherein m is about 0.1 to about 0.9; p is about 0.9 to about 0.1; n is about 10 to about 150; R 1 is independently (C 2 -C 20 ) alkylene, (C 2 -C 20 ) alkenylene, (C 2 -C 8 ) alkyloxy, (C 2 -C 20 ) alkylene, a residue of a saturated or unsaturated therapeutic diol, or a bicyclic-fragment of 1,4:3,6-dianhydrohexitol of formula (III): each R 2 is independently hydrogen, (C 1 -C 12 ) alkyl or (C 6 -C 10 ) aryl; the R 3 s, in an individual m monomer, are independently hydrogen, (C 1 -C 6 ) alkyl, (C 2 -C 6 ) alkenyl, (C 2 -C 6 ) alkynyl, or (C 6 -C 10 ) aryl (C 1 -C 6 ) alkyl; and R 4 is independently (C 2 -C 20 ) alkyl or (C 2 -C 20 ) alkenyl, wherein the composition has a molecular weight in the range from about 75,000 Da to about 200,000 Da, as measured by gel permeation chromatography and wherein the composition has a tensile strength at break in the range from about 20 MPa to about 150 MPa as measured by tensile measurement.
