In accordance with the present invention, there are provided free-radical polymerizable compositions comprising polycyclic olefins, wherein the polycyclic olefins contain little, if any, cyclopentenyl unsaturation. As a result, these olefins are sufficiently reactive with the propagating free-radicals during cure to provide a highly crosslinked thermoset resin. Moreover, invention compositions comprise high molecular weight polycyclic olefins having low volatility. Accordingly, the observed undesirable weight loss upon cure of prior art thermosetting compositions is considerably reduced. Further provided by the present invention are compositions comprising functionalized polycyclic olefin monomers. These functionalized olefin monomers provide additional benefits such as increased adhesion to a variety of surfaces and greater control over glass transition temperatures.
根据本发明,提供了由多环烯烃组成的可自由基聚合的组合物,其中多环烯烃几乎不含任何环戊烯不饱和度。因此,这些烯烃在固化过程中与传播的自由基有足够的反应性,从而提供高度交联的热固性树脂。此外,本发明组合物包含挥发性低的高分子量多环烯烃。因此,在固化现有技术的热固性组合物时所观察到的不良重量损失将大大减少。本发明还提供了包含官能化多环烯烃单体的组合物。这些官能化的烯烃单体具有更多的优点,例如增加了对各种表面的附着力,并能更好地控制玻璃化转变温度。
