Patent ID: 8779069

Claim:
A polymer comprising: a) at least one ethylene segment of structure 1 b) at least one substituted ethylene segment of structure 2 and c) at least one substituted ethylene segment of structure 3 wherein: x and y are independently integers from 10 to 30,000, and z is an integer from 1 to 10; R is independently at least one member selected from the group consisting of: —(CH 2 ) m N(CH 3 ) 2 , —(CH 2 ) n —(CH═CH)—(CH 2 ) r CH 3 , —(CH 2 ) v CH 3 , —(CH 2 ) p OH, —(CH 2 ) s N(CH 2 CH 2 OH) 2 , and —(CH 2 ) t OPO 3 H 2 ; R′ in structure 2 and R′ in structure 3 are independently H, —C q H 2q+1 , or —C q H 2q−k ; R″ is H or CH 3 ; R′″ is H, methyl, or phenyl; q, r, s, t, m, n, v, and p are each independently selected from the integers from 1 to 20; and k is the number of saturated hydrocarbon rings in —C q H 2q−k .
