  Various compositions encompassing polymers containing acidic pendent groups in combination with one or more reactive olefinic compounds and a photoacid generators form self-imagable negative tone films. Examples of such polymers include polymers and copolymers containing norbornene-type repeating units having acidic pendent groups, ring opened maleic anhydride polymers, polyacrylic acid, polyhydroxystyrene polymers, and the like. The films formed from such compositions provide self imagable, low-k, thermally stable layers for use in microelectronic and optoelectronic devices, among other applications.

  Embodiments in accordance with the present invention encompass a composition containing a latent catalyst and a compound capable of generating a Bronsted acid with a counterion capable of coordinating and activating the latent catalyst along with one or more monomers which undergo ring open metathesis polymerization (ROMP) and one or more multi-functional crosslinkable molecules when said composition is exposed to a suitable radiation forms a three-dimensional (3D) object. The catalyst system employed therein can be sensitive to oxygen and thus inhibits polymerization in ambient atmospheric conditions. The three-dimensional objects made by this process exhibits improved mechanical properties, particularly, high distortion temperature, impact strength, elongation to break, among others. Accordingly, compositions of this invention are useful as 3D inkjet materials for forming high impact strength objects of various sizes with microscale features lower than 100 microns, among various other uses.

  本发明的实施方案包括一种组合物，该组合物含有一种潜伏催化剂和一种能够生成具有反离子的勃朗斯特德酸的化合物，该反离子能够配位和活化潜伏催化剂以及一种或多种进行开环偏聚（ROMP）的单体和一种或多种多功能可交联分子，当所述组合物暴露在适当的辐射下时，就会形成三维（3D）物体。其中采用的催化剂系统可能对氧气敏感，因此在环境大气条件下会抑制聚合。通过这种工艺制作的三维物体具有更好的机械性能，特别是高变形温度、冲击强度和断裂伸长率等。因此，本发明的组合物可用作三维喷墨材料，用于形成具有低于 100 微米的微观特征的各种尺寸的高冲击强度物体，以及其他各种用途。

  Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound, a photosensitizer and one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to suitable actinic radiation to form a substantially transparent film or a three dimensional object. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several weeks and undergo mass polymerization only when subjected to actinic radiation under inert atmosphere such as for example a blanket of nitrogen. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as 3D printing materials, coatings, encapsulants, fillers, leveling agents, among others.
