| titleOfInvention | Background of the Invention Process for the preparation of dialkylidyl-capped polyalkylene glycols with in situ removal of 1,4-dioxane |
| abstract | (A) providing an epihalohydrin, a polyalkylene glycol containing an ethylene oxide component, and a Lewis acid; and (b) coupling the epihalohydrin to the polyalkylene glycol using the Lewis acid as a catalyst to produce a coupling product. (C) volatilizing 1,4-dioxane from the coupling product; (d) epoxidizing the coupling product by addition of a base and diglycidyl-capped polyalkylene glycol in the organic phase To produce a diglycidyl-capped polyalkylene glycol. |
