Abstract:
1. A polymer composition for forming a film comprising: a polymer comprising a first repeating unit represented by the Formula IIIb: where Z is O or NR and a phenol-functional norbornene second repeating unit derived from a phenol-functional monomer selected from the group of norbornene compounds consisting of: where n is an integer from 1 to 5, W is H or alkyl or alkoxy; each R said polymer being produced by reaction of said phenol functional norbornene monomer with a monomer represented by Formula II: where Z is defined as above, the reaction being characterized in that the amount of first repeating units represented by the Formula IIIb in the polymer is substantially equivalent to the amount of the monomer of the Formula II incorporated into the polymer; a casting solvent; and (i) a diazo-quinone functional photo active compound or (ii) a photo acid generator in combination with one or more crosslinking additives.
