A compound of the formula
- O[(CH.sub.2 CH.sub.2 O).sub.A (CH.sub.2 CH(CH.sub.3)O).sub.B CH.sub.2 CH(CH.sub.3)NH(COC(CH.sub.3)=CH.sub.2)].sub.2
- wherein A+B has an average value of about 2 to about 45.
A mixture of compounds of the formula ##STR9## wherein (A+B+D+E+F+G) has an average value of about 6 to about 35;
- A, B, D, E, F, G are all greater than or equal to 1;
- x, y, z are 0 or 1;
- provided if x=0, g is 1 and conversely g is 0 if x=1;
- if y=0, h is 1 and conversely h is 0 if y=1;
- if z=0, i is 1 and conversely i is 0 if z=1;
- provided further, at least one of x, y, z must be 1.
