First claim
Opening claim text (preview).
What is claimed is: 1. A compound of formula (I), wherein x is 1, y is 1, z is 0, R 1 and R 2 are each alkylenyl, and R 3 is hydrogen, and k, l, and m are each independently an integer selected from the group consisting of 0 to 25, wherein k+l+m is >0. 2. A compound of formula (I), wherein x is 1, y is 1, z is 0, R 1 and R 2 are each C 2 -alkylenyl, and R 3 is hydrogen, further wherein k, l, and m are each independently an integer selected from the group consisting of 0 to 25, wherein k+l+m is >0. 3. A compound of formula (I), wherein x is 1, y is 1, z is 0, R 1 and R 2 are each unsubstituted C 2 -alkylenyl, and R 3 is hydrogen, further wherein k, l, and m are each independently an integer selected from the group consisting of 0 to 25, wherein k+l+m is >0.
