摘要

A composition comprising a first divalent unit represented by formula:
and
at least one of
a second divalent unit represented by formula:
or
and
a monovalent unit selected from the group consisting of -S-C t H 2t+1 and -S-C r H 2r -A;
or
a monovalent unit represented by a formula selected from the group consisting of:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -S-C b H 2b OC(O)C b H 2b -P(O)(OY 2 ) 2 ;
and
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -S-C b H 2b-1 [OC(O)C b H 2b -P(O)(OY 2 ) 2 ,
wherein
R', R", and R"' are each independently hydrogen or alkyl having from 1 to 4 carbon atoms;
V is alkylene that is optionally interrupted by at least one ether linkage or amine linkage;
t is an integer having a value from 4 to 22;
r is an integer having a value from 2 to 10;
A is selected from the group consisting of -OH, -COOY 2 , and -SO 3 Y 2 ;
each Y 2 is independently selected from the group consisting of hydrogen, alkyl, and a counter cation; and
each b is independently an integer from 1 to 5. Methods of treating a surface using these compositions and articles with a surface in contact with these compositions are provided. Methods of making these compositions are also provided.
