Abstract
Disclosed is a polymeric product of diglycidyl bis phenol p-dialkyl benzene, and dicyanate diphenyl hexafluoro isopropane. Also disclosed is an organic polymeric dielectric composite of organic polymeric films, as polyimide films, dispersed in and reinforcing the organic polymeric adhesive reaction product of diglycidyl bis phenol p-dialkyl benzene, and dicyanate diphenyl hexafluoro isopropane. Further disclosed is an electronic circuit package that is adapted to receive at least one microelectronic circuit chip, with at least one layer having a substrate of an organic polymeric dielectric composite of organic polymeric films and the organic polymeric adhesive reaction product of diglycidyl bis phenol p-dialkyl benzene, and dicyanate diphenyl hexafluoro isopropane.
