  • Amide side-chain polymers
    Patent number: 4925589
    Abstract: Polymers having a monomeric unit of the formula ##STR1## wherein R.sup.1 represents hydrogen, methyl, ethyl, fluorine, chlorine, bromine, cyano or phenyl; X.sup.1 denotes oxygen, sulfur, --NH-- or --N(CH.sub.3)--; R.sup.2 is alkylene with 3-15 carbon atoms in which optionally a non-terminal methylene group is replaced by oxygen or sulfur; X.sup.2 denotes a single covalent bond, oxygen or sulfur; rings A and B each independently represent 1,4-phenylene which is unsubstituted or substituted with halogen, methyl, methoxy and/or cyano and in which optionally one CH group or two CH groups is/are replaced by nitrogen; ring C represents 1,4-phenylene which is unsubstituted or substituted with halogen, methyl, methoxy and/or cyano and in which optionally one CH group or two CH groups is/are replaced by nitrogen or represents trans-1,4-cyclohexylene; n stands for the number 0 and Z.sup.1 stands for --CONH-- or --NHCO--; or n stands for the number 1, one of the groups Z.sup.1 and Z.sup.
