Block copolymers occupy a huge area of research because they offer a vast range of possibilities for architecture, size, and chemical composition. Advances in polymer chemistry, such as anionic polymerisation and most recently living radical polymerization, have enabled a vast array of block copolymers to be synthesized with great control over their architecture, molecular weight, chemical composition, and functionality. Their intrinsic multi-properties allow the combination of different polymers and therefore the design of novel materials potentially comprising several different properties (e.g. thermoplastic, rubber, ductile, electrical conductivity, etc.).
