Descripción

General description

Poly [(phenyl glycidyl ether)-co-formaldehyde] (Re₂O₇) is a strong oxidant and a highly selective Lewis acid catalyst. The structure is constituted of strongly distorted ReO₄ octahedra and nearly regular ReO₄ tetrahedra which are connected through corners to form polymeric double layers in the ac plane.

Application

Re₂O₇ acts as a catalyst in the heteroacylative dimerization of THF.Adhesives, structural and electrical laminates and coatings and castings for high temperature service.

Features and Benefits

Good chemical resistance at high temperatures. Substitutes for Bisphenol A and phenolic epoxy resins.

Physical form

Oligomeric epoxide.
