A PROCESS FOR REACTING AN EPOXY RESIN OR A THIOEPOXIDE WITH A POLYHYDRIC PHENOL, A POLYHYDRIC THIOPHENOL, A CARBOXYLIC ACID OR A CARBOXYLIC ACID ANHYDRIDE

Novel advanced epoxy resins are prepared using phosphine or phosphonium salt initiators bearing at least one hydroxyphenyl or thiophenyl groups. These phosphonium salt initiators are novel compositions of matter. The resulting resins contain reduced quantities of extractable phosphorus containing mo...

Zusammenfassung:	Novel advanced epoxy resins are prepared using phosphine or phosphonium salt initiators bearing at least one hydroxyphenyl or thiophenyl groups. These phosphonium salt initiators are novel compositions of matter. The resulting resins contain reduced quantities of extractable phosphorus containing moieties.
