Patent ID: 8765894

Claim:
A ROMP norbornene-type polymer consisting essentially of: a first type of repeating unit derived from a norbornene-type monomer represented by Formula I: where for Formula I, m is from 0 to 3, at least one of R 1 , R 2 , R 3 and R 4 is the pendent group represented by Formula III: where for Formula III, R′ is selected from —(CH 2 ) p —, where p is from 0 to 12; Ar is an aromatic group having one or more aromatic rings; R″ is selected from —(CH 2 ) p — where p is as defined above, or —(CH 2 ) s —O—(CH 2 )— t —, where s and t are independently from 1 to 6, and R″ is coupled to the nitrogen of the quaternary ammonium functional group by a covalent bond, each of R a , R b and R c are independently selected from a methyl, an aryl or alkyl-aryl group where the alkyl is a C 1 to C 4 alkyl, and v is either 1 or 2, the others of R 1 , R 2 , R 3 and R 4 independently being a hydrogen, a C 1 to C 10 alkyl, an aryl or an alkyl-aryl group; and a second type of repeating unit derived from a norbornene-type monomer represented by Formula II: where for Formula II, m is as defined above and at least one of R 5 , R 6 , R 7 and R 8 is selected from a substituted or unsubstituted maleimide-alkyl pendent group where the alkyl is a C 1 to C 6 alkyl or NBCH 2 OCH 2 NB, NBCH 2 —(OCH 2 CH 2 ) 2 OCH 2 NB, NBCH 2 —(OCH 2 CH 2 ) 3 OCH 2 NB, NB-NB, NB-Et-NB, NB-Bu-NB, NB-Hx-NB, NBC 6 H 4 NB and NBCH 2 C 6 H 4 CH 2 NB, the others of R 5 , R 6 , R 7 and R 8 being independently selected from a hydrogen, a C 1 to C 11 alkyl or terminally halogenated alkyl, an C 1 to C 12 -alkyl-aryl where the aryl portion is optionally halogenated or a methyl glycol ether —CH 2 —(OCH 2 CH 2 ) q —OMe where q is from 1 to 4.
