Insoluble polyalkyl phosphonium salt resins having carbon-carbon crosslinked backbone

摘要

Novel resins having a carbon-to-carbon backbone, cross-linked with carbon-to-carbon linkages and having a plurality of pendant groups, wherein m is an integer from 1 to 6, preferably 3, each R is an alkyl group of from 1 to 10 C atoms, preferably 2-6 C atoms, and X is an alkoxyl or aryloxy group, an OH- group or a hydrocarbyl COO- group or a CN-, NO3-, SO4-, or ClO4- group and a method of their preparation are disclosed. The cross-linked resins are useful as resins and as insoluble catalysts for preparation of glycol ethers from alcohols and epoxides, and for polymerizing epoxides.
