Claim:
A co-polymer composition comprising at least one co-polymer selected from a member of the group consisting of: (A) a PEA of structural formula (I): wherein m is about 0.01 to about 0.99; p is about 0.99 to about 0.01; and n is about 5 to about 100; and wherein R 1 is independently selected from the group consisting of (C 2 -C 20 ) alkylene, (C 2 -C 20 ) alkenylene, and combinations thereof; R 3 s and R 4 s in a single co-monomer m or p, respectively, are independently selected from the group consisting of hydrogen, (C 1 -C 6 ) alkyl, (C 2 -C 6 ) alkenyl, (C 2 -C 6 ) alkynyl, (C 6 -C 10 ) aryl (C 1 -C 6 ) alkyl and —(CH 2 ) 2 S(CH 3 ); R 5 is selected from bicyclic-fragments of 1,4:3,6-dianhydrohexitols of structural formula (II); and R 6 is selected from the group consisting of (C 2 -C 20 ) alkylene, (C 2 -C 20 ) alkenylene or alkyloxy; and (B) a PEA of structural formula (III): wherein m is about 0.01 to about 0.99; p is about 0.99 to about 0.01; q is about 0.99 to 0.01; and n is about 5 to about 100; and wherein R 1 is independently selected from the group consisting of (C 2 -C 20 ) alkylene, (C 2 -C 20 ) alkenylene, and combinations thereof; R 3 s and R 4 s in a single co-monomer m or p, respectively, are independently selected from the group consisting of hydrogen, (C 1 -C 6 ) alkyl, (C 2 -C 6 ) alkenyl, (C 2 -C 6 ) alkynyl, (C 6 -C 10 ) aryl (C 1 -C 6 ) alkyl and —(CH 2 ) 2 S(CH 3 ); R 5 is selected from bicyclic-fragments of 1,4:3,6-dianhydrohexitols of structural formula (II); R 6 is selected from the group consisting of (C 2 -C 20 ) alkylene, (C 2 -C 20 ) alkenylene or alkyloxy; R 7 is hydrogen, (C 6 -C 10 ) aryl (C 1 -C 6 ) alkyl or a protecting group; and R 8 is independently (C 1 -C 20 ) alkyl or (C 2 -C 20 ) alkenyl
