Abstract:
An amide-group-containing polyacetal, having acetal structure unit (1) of general formula (1) below in its molecule,wherein general formula (1) is ##STR8## wherein: R.sup.1 denotes at least one member selected from the group consisting of a hydrogen atom, a methyl group, an ethyl group, and a halogen atom; R.sup.2 and R.sup.3 are both at least one member selected from the group consisting of a hydrogen atom, alkyl groups with 1 to 18 carbon atoms, alkenyl groups with 2 to 18 carbon atoms, aromatic groups having at least one benzene ring, alkoxy groups (2) of general formula (2) below, and substituted alkyl groups (4) of general formula (4) below, and may be the same as each other at the same time or different from each other, wherein the alkyl groups, the alkenyl groups, and the benzene ring all may contain a substituent;and wherein general formula (2) isR.sup.4 --O .paren open-st.C.sub.m H.sub.2m O .paren close-st..sub.1( 2)wherein: R.sup.4 denotes at least one member selected from the group consisting of a hydrogen atom, alkyl groups, and aromatic groups having at least one benzene ring; m is 2 to 4; and l is 1 or more;and wherein general formula (4) isA .paren open-st.CH.sub.2 .paren close-st..sub.n ( 4)wherein: A denotes at least one member selected from the group consisting of SO.sub.3 H, SO.sub.3 Na, SH and NR.sup.6 R.sup.7, wherein R.sup.6 and R.sup.7 are both at least one member selected from the group consisting of a hydrogen atom, alkyl groups with 1 to 18 carbon atoms, alkenyl groups with 2 to 18 carbon atoms, and aromatic groups having at least one benzene ring, and may be the same as each other at the same time or different from each other, wherein the alkyl groups, the alkenyl groups, and the benzene ring all may contain a substituent; and n is 1 to 4.
