AMPHIPHATIC COIL-ROD TYPE 2-VINYLPYRIDINE/N-HEXYLISOCYANATE BLOCK COPOLYMER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an amphiphatic coil-rod type 2-vinylpyridine/n-hexylisocyanate block copolymer, and to provide its polymerization method. SOLUTION: This amphiphatic coil-rod type 2-vinylpyridine/n-hexylisocyanate block copolymer synthesized by a series of polymerization method comprising a step for synthesizing poly(2-vinylpyridine) having a narrow mol. wt. distribution by a living polymerization method using potassium diphenylmethane (K-DPM) as a polymerization initiator, a step for adding sodium tetraphenylborate (NaBPh4) to the product to exchange the counter cation for sodium ion (Na+), and a step for adding n-hexylisocyanate to the product and polymerizing the mixture to synthesize the block copolymer. A polymerization method thereof is also disclosed. COPYRIGHT: (C)2006,JPO&NCIPI
