Embodiments in accordance with the present invention encompass compositions encompassing a procatalyst and a thermal or photoactivator along with one or more monomers which undergo vinyl addition polymerization when said composition is heated to a temperature from 50° C. to 100° C. to form a substantially transparent film. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.
根据本发明的实施方案,本发明的组合物包括一种催化剂和一种热活化剂或光活化剂,以及一种或多种单体,当所述组合物加热到 50° C 至 100° C 的温度时,这些单体发生
乙烯基加成聚合反应,形成基本透明的薄膜。其中使用的单体的折射率范围为 1.4 至 1.6,因此这些组合物可以定制以形成不同折射率的透明薄膜。因此,本发明的组合物可用于各种光电子应用,包括用作涂层、封装剂、填料、匀染剂等。
