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.
