ABSTRACT:
The invention is a bis-BCB compound of the structure: ##STR1## a method for making same and polymers made therefrom. The novel compounds of this invention are useful in preparing polymers that can form thin film coatings for multichip midules (MCMs) and integrated circuits (ICs). These compounds can be isolated as liquids at room temperature, and can form polymers that are hydrophobic and have low dielectrical and dissipative properties.
