摘要:
Polytetrahydrofuran vinyl ethers of the general formulaH.sub.2 C.dbd.HC--[)O--CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --].sub.n O--R Iwhere R is hydrogen or the CH.dbd.CH radical and n is from 2 to 150, are prepared by a process in which polytetrahydrofuran of the general formulaH--[O--CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --].sub.n OH IIis reacted with acetylene.
