Embodiments in accordance with the present invention encompass compositions containing one or more polycycloolefinic monomers, optionally at least one multifunctional olefinic monomer and a suitable solvent, which exhibits long shelf life stability and undergoes mass polymerization only when subjected to a suitable temperature to provide a three-dimensional insulating articles. Embodiments of this invention exhibit hitherto unattainable properties, such as for example, low dielectric constant and low loss properties, and very high thermal properties, among others. 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. In general the compositions are stable at room temperature for an extended period of time lasting up to a few weeks 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.
