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.

In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprise 10-70 wt. % or 20-40 wt. % of a cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises an acrylate moiety and an ethenyl or ethynyl moiety, and the α-carbon of the acrylate moiety and the α-carbon of the ethenyl or ethynyl moiety may have a 1,5-, 1,6-, 1,7-, or 1,8-relationship. Additionally, an ink described herein can have a viscosity of 1600 centipoise (cP) or less at 30° C., or of 500 cP or less at 30° C. and can be used to print a desired 3D article having mechanical properties similar to those of articles formed from thermoplastic materials.
