Patent ID: 7799883

Claim:
A non-self imageable polymer consisting of norbornene-type repeating units, said polymer comprising: a first norbornene-type repeating unit represented by Formula I: where X is —CH 2 —, CH 2 CH 2 —, O or S; n is an integer from 0 to 5 inclusive; each of R 1 to R 4 independently represents hydrogen, a linear or branched alkyl group, or a linear or branched haloalkyl group, subject to the proviso that at least one of R 1 to R 4 is a -QNHSO 2 R 5 group where Q is a linear or branched alkyl spacer of 1 to 5 carbons, and R 5 is a perhalo group of 1 to 10 carbon atoms; and a second type of norbornene-type repeating unit represented by Formula II: where X and n are as defined for Formula I and each of R 6 to R 9 independently represents hydrogen, a linear or branched alkyl group, or a linear or branched haloalkyl group, subject to the proviso that at least one of R 6 to R 9 is where Q is an optional, linear or branched alkyl spacer where if present is of 1 to 5 carbons, m is either 0 or an integer from 1 to 3 inclusive; and R 10 is a linear or branched perhalo alkyl of 1 to 10 carbon atoms.
