Embodiments in accordance with the present invention encompass compositions containing one or more polycycloolefinic monomers and at least one multifunctional olefinic monomer which when subjected to a suitable temperature undergoes mass polymerization to provide a three-dimensional insulating article which exhibits hitherto unattainable low dielectric constant and low-loss properties, and very high thermal properties. The compositions of this invention may additionally contain one or more organic or inorganic filler materials, which provide improved thermo-mechanical properties in addition to very low dielectric properties. The compositions are stable at room temperature and undergo mass polymerization only when subjected to suitable higher temperatures generally above 100° C. The compositions of this invention are useful in various applications, including as insulating materials in millimeter wave radar antennas, among others.
