Abstract:
A polymer containing repeat units derived from a norborne sulfonamide monomer having the formula wherein x represents oxygen, nitrogen with hydrogen or a C1-10 alkyl linear or branched being bonded thereto, sulfur or a methylene group of the formula â€”(CH2)nâ€²â€”; nâ€² is an integer of 1 to 5; n is an integer of 0, 1 or more and R1 and R4 independently represent hydrogen, linear or branched linear and branched C1-C20 alkyl; R2 and R3 independently represent hydrogen, linear and branched C1-C20 alkyl or a sulfonamide group, with the proviso that at least one of R2 and R3 is a pendant sulfonamide group of the formulae:â€”Aâ€”NRâ€²SO2Râ€³ and â€”Aâ€”SO2NRâ€²Râ€²â€³or a cyclic sulfonamide group formed by combining R2 and R3 together with the two ring carbon atoms to which they are attached to form a heterocyclic ring of the formula: wherein m is an integer from 1 to 3;Râ€² represents hydrogen, linear and branched tri(C1-C10) alkylsilyl, â€”C(O)CF3, â€”C(O)OR, and â€”OC(O)OR, wherein R is linear and branched C1-C10 alkyl, linear and branched C1-C10 haloalkyl, substituted and unsubstituted C6-C14 aryl, and substituted and unsubstituted C7-C20 aralkyl; Râ€³ represents linear and branched C1-C10 alkyl, linear and branched C1-C10 haloalkyl, â€”C(O)OR, â€”(CHR1â€²)nâ€²â€”OR, â€”(CHR1â€²)nâ€²â€”C(O)R, substituted and unsubstituted C3 to C8 cycloalkyl cyclic esters (lactones) containing 2 to 8 carbon atoms (not counting the carbonyl carbon), cyclic ketones containing 4 to 8 carbon atoms (not counting the carbonyl carbon), cyclic ethers and cyclic diethers containing 4 to 8 carbon atoms, wherein R is as defined above, R1â€²is as defined below and nâ€³ represents an integer from 1 to 10; Râ€²â€³ represents hydrogen, linear and branched C1-C10 alkyl, linear and branched C1-C10 haloalkyl, â€”C(O)OR, â€”(CHR1â€²)nâ€³â€”OR, â€”(CHR1â€²)nâ€³â€”C(O)R, substituted and unsubstituted C3 to C8 cycloalkyl, cyclic esters (lactones) containing 2 to 8 carbon atoms (not counting the carbonyl carbon), cyclic ketones containing 4 to 8 carbon atoms (not counting the carbonyl carbon), cyclic ethers and cyclic diethers containing 4 to 8 carbon atoms, wherein R is as defined above, R1â€² is as defined below, and nâ€³ is as defined above; â€”Aâ€” represents a divalent radical selected from the group consisting of â€”(CR1â€²R2â€²)nâ€³â€”; â€”(CHR1â€²)nâ€³O(CHR1â€²)nâ€³â€”; â€”(CHR1â€²)nâ€³C(O)O(CHR1â€²)nâ€³â€”; â€”(CHR1â€²)nâ€³C(O)(CHR1â€²)nâ€³â€”; C3-C8 cycloalkyl; C6-C14 aryl; cyclic ethers and cyclic diethers containing 4 to 8 carbon atoms, wherein nâ€³ represents an integer from 1 to 10, and R1â€² and R2â€² independently represent hydrogen, linear and branched C1-C10 alkyl and halogen, and the group â€”(CHR1â€²)nâ€³OC(O)â€” but only when the sulfonamide group is â€”NRâ€²SO2Râ€³; and optionally one or more norbornene-type monomer(s) represented by the formula wherein R5 to R8 independently represents a hydrocarbyl or a functional substituent and n is an integer of 0 or 1 or more.
