Abstract: Disclosed is an azetidinium-containing copolymer comprising: (a) monomeric units derived from at least one vinylic monomer selected from the group consisting of a carboxyl-containing vinylic monomer, an amino-containing vinylic monomer, and combination thereof; and (b) azetidinium-containing monomeric units derived from at least one azetidinium-containing vinylic monomer of formula (1) or (2) in which: R” is hydrogen or methyl; T7 and T8 independent of each other are C1 to C14 alkyl group; Y1, Y2, and Y3 independent of one other are a linkage selected from the group consisting of a direct bond, –O–, –NR’–, –C(O)–NR’–, –NR’–C(O)–, –O–C(O)–NH–, –NH–C(O)–O–, –NR’–C(O)–NH–, –NH–C(O)–NR’–, –C(O)–O–, –O–C(O)–, –NH–C(O)–NH–Z0–NH–C(O)–NH–, –O–C(O)–NH–Z0–NH–C(O)–O–, –O–C(O)–NH–Z0–NH–C(O)–NH–, and –NH–C(O)–NH–Z0–NH–C(O)–O–; R’ is hydrogen, a linear or branched C1-C20 alkyl group; Z0 is a linear or branched C2-C12 alkylene divalent radical or a C5-C45 cycloaliphatic or aliphatic-cycloaliphatic divalent radical optionally containing therein one or more linkages of –O–, –NR’– and –C(O)–, R’ is as defined above; Z1, Z2, and Z3 independent of one other are a direct bond, a linear or branched C1-C20 alkylene divalent radical optionally containing therein one or more linkages of –O–, –NR’–, and –C(O)–, a C1–C7 alkyleneoxy C1–C7 alkylene divalent radical, a divalent radical of –(CH(R’’)CH2O)r1–CH(R’’)CH2– in which R’’ is as defined above and r1 is an integer of 1 to 20, a phenylene divalent radical, C1-C4 alkyl or C1-C4 alkoxy substituted phenylene divalent radical or C7-C12 arakylene divalent radical, a C5-C45 cycloaliphatic or aliphatic-cycloaliphatic divalent radical optionally containing therein one or more linkages of –O–, –NR’–,and –C(O)–, a C6-C24 aromatic or araliphatic divalent radical, or combinations thereof; p1, p2, and p3 independent of one another are zero or 1; Y4 is a linkage selected from the group consisting of a direct bond, –O–, –NR’–, –C(O)–NR’–, –NR’–C(O)–, –O–C(O)–NH–, –NH–C(O)–O–, –NR’–C(O)–NH–, –NH–C(O)–NR’–, –C(O)–O–, –O–C(O)–, R’ is hydrogen, a linear or branched C1-C20 alkyl group; Z4, is a direct bond, a linear or branched C1-C20 alkylene divalent radical optionally containing therein one or more linkages of –O–, –NR’–, and –C(O)–, a C1–C7 alkyleneoxy C1–C7 alkylene divalent radical, or a divalent radical of –(CH(R’’)CH2O)r1–CH(R’’)CH2– in which R’’ is as defined above and r1 is an integer of 1 to 20; and Z5 is a linear or branched C1-C20 alkyl group, –(CH2)r2–O–(CH2CH2O)r1–Z6 in which r1 is as defined above, r2 is zero or an integer of 1 to 7, and Z6 is a C1-C5 alkyl. Also disclosed is an azetidinium-containing vinylic monomer of formula (2) in which: R” is hydrogen or methyl; p1, p2, and p3 independent of one another are zero or 1; Y4 is a linkage selected from the group consisting of a direct bond, –O–, –NR’–, –C(O)–NR’–, –NR’–C(O)–, –O–C(O)–NH–, –NH–C(O)–O–, –NR’–C(O)–NH–, –NH–C(O)–NR’–, –C(O)–O–, –O–C(O)–, R’ is hydrogen, a linear or branched C1-C20 alkyl group; Z4, is a direct bond, a linear or branched C1-C20 alkylene divalent radical optionally containing therein one or more linkages of –O–, –NR’–, and –C(O)–, a C1–C7 alkyleneoxy C1–C7 alkylene divalent radical, or a divalent radical of –(CH(R’’)CH2O)r1–CH(R’’)CH2– in which R’’ is as defined above and r1 is an integer of 1 to 20; and Z5 is a linear or branched C1-C20 alkyl group, –(CH2)r2–O–(CH2CH2O)r1–Z6 in which r1 is as defined above, r2 is zero or an integer of 1 to 7, and Z6 is a C1-C5 alkyl.
