The temperature required to induce cross-linking in typical benzocyclobutene-based thermosets is near 250 °C, which exceeds the use of many chemical components. A new and versatile synthesis BCB-functionalized monomers has allowed access that can be incorporated into a variety macromolecular platforms enable significantly reduced cure temperatures. Incorporation comonomers polystyrene polynorbornene enabled insolublization thin films by curing at only 120 °C for 1 h.
