Preparation and distorted cylindrical morphology of block copolymers consisting of flexible and semiflexible blocks

Diblock copolymers consisting of flexible polystyrene and semiflexible poly( n -hexyl isocyanate), P(S- b -HIC)s, were prepared by anionic polymerization, followed by size-exclusion chromatography (SEC) fractionation. Two P(S- b -HIC) samples having PHIC volume fractions ( Φ PHIC ) of 0.18 and 0.31,...

Zusammenfassung:	Diblock copolymers consisting of flexible polystyrene and semiflexible poly( n -hexyl isocyanate), P(S- b -HIC)s, were prepared by anionic polymerization, followed by size-exclusion chromatography (SEC) fractionation. Two P(S- b -HIC) samples having PHIC volume fractions ( Φ PHIC ) of 0.18 and 0.31, sufficiently high molecular weights ( M n,PS and M n,PHIC are both larger than 10 kg/mol), and narrow molecular weight distributions ( M w / M n
