First Claim
Patent Images
1. A signal transmission component comprising:
- a) a signal transmission device; and
b) a dielectric encapsulant which encapsulates said device, said encapsulant having a C-H adhesion value of at least 4.0 comprising;
the extended reaction product of an admixture of;
a) an effective amount of an anhydride functionalized compound having reactive anhydride sites; and
b) an effective amount of a crosslinking agent which reacts with the anhydride sites of said compound to form a cured crosslinked material;
said reaction product extended with at least one organic plasticizer present in the range of between 5 and 95 percent by weight of said encapsulant to form a plasticized system which is essentially inert to the reaction product and substantially non-exuding therefrom.
