Azetidinium-containing copolymers and uses thereof

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 monomer...

Beschreibung
Zusammenfassung:	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
