Polycyclic polymers containing pendant ion conducting moieties

An addition polymer comprising polycyclic repeating units having the structural formula:

• wherein X represents —CH2—, —CH2CH2—, O, or S;
• n is an integer from 0 to 5 inclusive;
• R1 to R4 independently represent hydrogen or a pendant group selected from linear and branched (C1 to C20) alkyl, linear and branched (C1 to C20) haloalkyl, or a pendant ion conducting moiety and salts thereof selected from sulfonic acid, phosphoric acid, carboxylic acid moieties and combinations thereof represented by the formulae:
• -(A)q-SO3H
• -(A)q-OP(O)(OH)(OR)
• -(A)q-P(O)(OH)(OR)
• —(CH2)mC(O)OH
• wherein A is a spacer moiety represented by —(CH2)m—, —(CH2)mO—, —(CH2)mO(CH2)m—, —O(CH2)m—, —(CH2)mNR15(CH2)m—, —(CH2)m-aryl-, —O(CH2)m-aryl-, —(CH2)mO(CH2)m-aryl-, -aryl-O(CH2)m—, -aryl-NR15(CH2)m—, —(C(R16)2)m(C(R16)2)mO(C(R17)2)a—, and
• wherein aryl represents phenyl, naphthyl, and anthracenyl, R is selected from hydrogen, linear and branched (C1 to C10) alkyl, linear and branched (C1 to C10) haloalkyl, and substituted and unsubstituted (C6-C16) aryl;
• R15 independently is selected from hydrogen and (C1 to C5) alkyl, R16 independently is selected from hydrogen, halogen, (C1 to C5) alkyl, and (C1 to C5) haloalkyl, R17 independently is selected from hydrogen and halogen, R18 is selected from hydrogen and (C1 to C10) alkyl and (C1 to C5) haloalkyl;
• a is 2 to 6;
• m independently is 0 to 4 and q is 0 or 1, subject to the proviso that for at least that a portion of such repeating units at least one of R1 to R4 is a phosphoric acid moiety not directly connected to an oxygen atom on said spacer moiety.
