An article comprising a lignin derivative, wherein the lignin derivative comprises one or more polycations.
A method of inhibiting microbial growth, the method comprising:
- contacting one or more microbes with an article comprising a lignin derivative, wherein the lignin derivative is represented by Formula I:
- wherein:
- G1 is absent or a polymerizable group;
- G is absent or a polymeric group;
- R1 is a bond, alkylene, (alkyleneamino)q, (alkyleneoxy)q, (alkyleneoxyarylene)q or (alkyleneoxyarylene)alkylene (aryleneoxyalkylene)q moiety, wherein q is from 1 to 10;
- R2 is H or alkyl;
- and
- R3 is a polycation.
(canceled)
A method for preparing a lignin derivative, the method comprising:
- contacting a lignin-containing material with one or more groups of Formula II or IIA:
- to form the lignin derivative wherein the lignin derivative is represented by Formula I:
- wherein:
- G1 is absent or a polymerizable group;
- G is absent or a polymeric group;
- LG is a leaving group;
- R1 is a bond, alkylene, (alkyleneamino)q, (alkyleneoxy)q, (alkyleneoxyarylene)q or (alkyleneoxyarylene)alkylene (aryleneoxyalkylene)q moiety, wherein q is from 1 to 10;
- R2 is H or alkyl;
- and
- R3 is a polycation.
25-46. (canceled)
A method of coating an article with a lignin derivative, wherein the method comprises contacting an article with one or more groups of Formula I:
- wherein:
- G1 is absent or a polymerizable group;
- G is absent or a polymeric group;
- R1 is a bond, alkylene, (alkyleneamino)q, (alkyleneoxy)q, (alkyleneoxyarylene)q or (alkyleneoxyarylene)alkylene (aryleneoxyalkylene)q moiety, wherein q is from 1 to 10;
- R2 is H or alkyl;
- and
- R3 is a polycation.
