Patent ID: 8716420

Claim:
An amphiphilic polymer (A) comprising repeat units of the general formulae (I), (II) and (III): or salts thereof, wherein the repeat unit of general formula (I) is comprised in the amphiphilic polymer with a number of m units, the repeat unit of general formula (II) is comprised in the amphiphilic polymer with a number of o units and repeat unit of general formula (III) is comprised in the amphiphilic polymer with a number of p units, wherein each of m, o and p is an independently selected integer from about 3 to about 400 and wherein the sum of m+o+p is selected in the range from about 10 to about 10000, R 1 in repeat units (I)-(III) is H or methyl, R 2 in repeat unit (II) is an aliphatic moiety with a main chain of about 3 to about 30 carbon atoms and 0 to about 3 heteroatoms selected from the group N, O, S, Se and Si, and, R 3 in repeat unit (III) is one of (i) an alicyclic moiety with a main chain of about 5 to about 80 carbon atoms and 0 to about 30 heteroatoms selected from the group N, O, S, Se and Si, and, (ii) a moiety —Z—R 4 wherein R 4 is an alicyclic moiety with a main chain of about 5 to about 80 carbon atoms and 0 to about 30 heteroatoms selected from the group N, O, S, Se and Si and Z is an aliphatic bridge of 1 to 3 carbon atoms and 0 to about 2 heteroatoms selected from group of N, O, S, Se and Si, (iii) an aliphatic moiety with a main chain of about 3 to about 80 carbon atoms and 0 to about 30 heteroatoms selected from the group N, O, S, Se and Si, and a C≡C group or an azido group.
