Abstract
Three different cases of reactions using end-groups in polymers were analyzed for the synthesis of block copolymers, such as: a) azide (RN3) and alkine (RCCH) end groups to obtain a 1,3-dipolar cycloaddition (click chemistry), b) α,ω-hydroxy telechelic polymers (HOROH) and diisocyanates (OCNRNCO) to synthesize polyurethanes by polycondesation and c) alkyl halides (RCl or RBr) to prepare block copolymers derived of polystyrene by atom transfer radical polymerization (ATRP).
