Abstract

Various vinyl addition polymers of nadic anhydride are disclosed. Examples of such polymers include copolymers and terpolymers of nadic anhydride with a wide variety of norbornene-type monomers. The nadic anhydride polymers are found to be useful in forming a wide variety of photosensitive compositions, both positive and negative, which are capable of forming high resolution imagable films exhibiting excellent dielectric properties (low-k) and thermal properties, and thus are useful in the fabrication of a variety of microelectronic and optoelectronic devices, among others.
