Benzocyclobutenes constitute the basis of a new and versatile approach to the synthesis of high performance polymers for applications in the electronics and aerospace industries. The basic technology involves a family of thermally polymerizable monomers which contains one or more benzocyclobutene groups per molecule. The benzocyclobutene when heated to 200°C undergoes a retrocyclic opening of the aliphatic four membered ring to afford the highly reactive o‐xylylene, which can either react with itself, or react with other sites of unsaturation leading to the formation of thermally stable polymers. Depending upon their functionality, these monomers can be polymerized to yield either thermoset or thermoplastic materials. The polymers typically exhibit good thermal stability and retention of mechanical properties at elevated temperature. The monomers are processable from the melt and are useful in the preparation of high temperature coatings, advanced composites and adhesives.
