Claim 21:
22. The method according to claim 21, wherein the first monomer comprises the formula:, wherein: R5 is selected from the group consisting of: hydrogen; C1-20 alkyl, optionally substituted; heterocyclyl, optionally substituted; aryl, optionally substituted; heteroaryl, optionally substituted; and cyano;
R6 is selected from the group consisting of: hydrogen; C1-20 alkyl, optionally substituted; heterocyclyl, optionally substituted; aryl, optionally substituted; a heteroaryl, optionally substituted; and cyano; and
R7 is selected from the group consisting of hydrogen and C1-20 alkylene, optionally substituted;
wherein: when R7 is hydrogen, R8 is not present; and when R7 is not hydrogen, R8 is selected from the group consisting of: —N(Ra′)Ra″; —C(O)N(Rb′)Rb″; —P(Rc′)Rc″; and —S(Rd′);
wherein: Ra′, Ra″, Rb′, Rb″, Rc′, Rc″ and Rd′ are independently selected from the group consisting of: hydrogen; halo; C1-20 alkyl, optionally substituted; heterocyclyl, optionally substituted; aryl, optionally substituted; alkyl-aryl, optionally substituted; and heteroaryl, optionally substituted; and, alternatively, Ra′ and Ra″; or Rb′ and Rb″; or Rc′ and Rc″; are linked together to form, together with the hetero atom to which they are attached, a 4- to 7-membered ring, which ring optionally contains one further heteroatom and which ring optionally is substituted by one or more groups selected from halo and ═O.
