Multifunctional zwitterionic polymer conjugates

A random copolymer of Formula I:

• wherein
• each M1 and M2 are independently selected from the group consisting of acrylate, methacrylate, acrylamide, methacrylamide, styrene, vinyl-pyridine and vinyl-pyrrolidone;
• R1 is selected from the group consisting of H, L1-A1, LG1 and L1-LG1;
• each R2 is independently selected from the group consisting of H, C1-20 alkyl, C2-6 alkenyl, C2-6 alkynyl, C1-6 haloalkyl, C1-6 heteroalkyl, C3-8 cycloalkyl, C3-8 heterocycloalkyl, aryl, heteroaryl, A2, L2-A2, LG2, L2-LG2, I2 and L2-I2;
• ZW is a zwitterionic moiety;
• I is an initiator fragment and I′ is a radical scavenger, such that the combination of I-I′ is an initiator, I1, for the polymerization of the random copolymer of Formula I;
• alternatively, I′ is selected from the group consisting of H and C1-6 alkyl;
• I2 is an initiator;
• each of L1 and L2 is a linker;
• each of A1 and A2 is a functional agent;
• each of LG1 and LG2 is a linking group;
• subscripts x and y1 are each independently an integer of from 1 to 1000;
• subscript z is an integer of from 1 to 10;
• subscript s is an integer of from 1 to 100;
• subscript n is an integer of from 1 to 20;
• and
• wherein either R1 is L1-A1 or one of R2 is L2-A2.
