Zusammenfassung:Improved methods for forming substituted polymers having a high degree of conjugation include the steps of activating a steric hindrance molecule under conditions that ensure substantially all the steric hindrance molecules are mono-activated and then reacting with a polymer. An improved method for recovering polypeptides substituted with steric hindrance molecules and having an elongate configuration removes impurities and volatiles without achieving complete dryness of the copolymer.
