Abstract
Various polycycloolefinic polymers containing phenolic pendent groups and compositions thereof useful for forming self-imageable films encompassing such polymers are disclosed. Such polymers encompass norbornene-type repeating units containing phenolic pendent groups which contain very low levels of fluorine containing monomers. The films formed from such polymer compositions provide self imageable, low-k, thermally stable layers for use in microelectronic and optoelectronic devices.
