摘要：

A rod-coil-rod block copolymer, polyhexylisocyanate-block-polystyrene-block-polyhexylisocyanate, of controlled molecular weight was synthesized quantitatively via living anionic polymerization using potassium naphthalenide in the presence of sodium tetraphenylborate. The use of K+ as the counterion for the polymerization of styrene, and Na+ (NaBPh4) for the polymerization of isocyanate leads to the formation of a well-controlled novel triblock copolymer.
