Patent ID: 8580911

Claim:
A polymer composition comprising a block copolymer having a formula: where X is selected from the group consisting of: halogen; —OH; azide, nitrile, and —OR z ; each R a , R b , R c , and R d is independently selected from the group consisting of: hydrogen, halogen, —CH 2 OR z , optionally substituted C 1-10 aliphatic, optionally substituted 6- to 14-membered aromatic, optionally substituted 3- to 14-membered heterocyclic, and optionally substituted 5- to 14-membered heteroaryl, and where any two or more of R a , R b , R c , and R d may be taken together to form an optionally substituted 3- to 12-membered ring, optionally containing one or more heteroatoms; L is a bond or a polyfunctional moiety; B is a hydrophilic oligomer having from about 4 to about 100 repeating units; n is an integer between 4 and 100; R z is selected from the group consisting of R 10 , —C(O)R 10 ,—SO 2 R 10 , —Si(R 10 ) 3 , —C(O)N(R 10 ) 2 ; and R 10 is an optionally substituted moiety selected from the group consisting of: C 1-20 aliphatic; C 1-12 heteroaliphatic; 6- to 14-membered aryl; and 5- to 14-membered heteroaryl.
