Abstract
Copolymers and compositions thereof useful for forming self-imageable films encompassing such copolymers are disclosed. Such copolymers encompass norbornene-type repeating units and maleic anhydride-type repeating units where at least some of such and maleic anhydride-type repeating units have been ring-opened. The films formed from such copolymer compositions provide self imageable, low-k, thermally stable layers for use in microelectronic and optoelectronic devices.
