본 발명에 따른 실시형태는 1종 이상의 폴리시클로올레핀 단량체와 적어도 1종의 다관능성 올레핀 단량체를 함유하며, 적절한 온도에서는 덩이중합을 일으켜 3D 절연성 물품을 제공하는 조성물에 관한다. 상기 물품은 종래 기술로는 실현하지 못한 낮은 유전상수, 저손실 특성, 매우 높은 열적 성질을 가진다. 본 발명의 조성물은 매우 낮은 유전특성과, 아울러 개선된 열기계적 특성을 제공하는 1종 이상의 유기 또는 무기 충전재 물질을 추가로 함유해도 좋다. 해당 조성물은 실온에서 안정적이며 일반적으로 100℃ 이상의 적절한 고온에 노출되었을 때만 덩이중합을 일으킨다. 본 발명의 조성물은 다양한 용도에서 사용이 가능하며, 개중에서도 밀리미터파 레이더 안테나의 절연 물질에 유용하다. 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.
