Abstract
Homogeneous thermosetting copolymers comprising a mixture of styrene-terminated tetrakisphenols and compounds containing at least one pendant vinyl group as exemplified by styrene-terminated tetrakisphenol ethane and styrene-terminated bisphenol A will possess desirable characteristics such as low dielectric constants and high glass transition temperatures. These polymers may be utilized as a component in laminates or circuit boards which are employed in relatively complicated pieces of electronic equipment.
