Synthesis of vinyl ether‐capped telechelic poly(tetrahydrofuran)

Abstract Vinyl ether‐terminated telechelic poly(tetrahydrofuran) (poly(THF)) was synthesized by the reaction of a bifunctional living cationic polymer of THF with an excess of Na⊕⊖OCH 2 CH 2 OCHCH 2 in THF at 0°C. The obtained polymer has narrow molecular weight distribution and end functionality close to two.
