An initiator for the terminal group of the polymer product of an atom or group radical transfer polymerisation has an activated carboxyl or an amine group which is reacted with an amine or carboxyl (respectively) group containing biologically active compound. The initiator is preferably 4-(3-(2-bromo, 2-methyl-propionate)phenyl)-propionic acid N-hydroxysuccinimide ester or 2-bromo, 2-methyl-propionic acid N-hydroxysuccinimide ester. The monomers preferably comprise a zwitterionic monomer such as 2-methacryloxyethyl-2′-trimethyl ammoniumethyl phosphate inner salt.
聚合物产品的末端基团的引发剂具有激活的羧酸或胺基团,该羧酸或胺基团与含有生物活性化合物的胺基或羧酸(分别)基团反应。该引发剂最好是4-(3-(2-溴,2-甲基丙酸酯)苯基)-丙酸N-羟基琥珀酰亚胺酯或2-溴,2-甲基丙酸N-羟基琥珀酰亚胺酯。单体最好包括离子对单体,如2-甲基丙烯酰氧基乙基-2'-三甲基氨基乙基磷酸内盐。
