ABSTRACT:
Epoxy resins have been reacted with a copolymer of a diunsaturated aliphatic compound and acrylonitrile or methacrylonitrile and a siloxane-containing polymer resulting in a rubber modified epoxy resin suitable for use in electrical and electronic component encapsulation formulations which provide such components with improved thermal shock performance. The rubber modified epoxy resins have improved flexural properties with minimal reduction in glass transition temperature.
