- a cycloalkylene group,
- a cycloalkenylene group, and
- an arylene group;
- R4 is a hydrocarbyl group containing 8-24 carbon atoms or a group represented by the formula R6—O-(A′O)w-T-,
- wherein

- R5 is a hydrocarbyl group or a benzyl group;
- X is a halogen, sulfate, or a carbonate;
- AO is an alkyleneoxy group containing 2-4 carbon atoms;
- n is an integer of between 1 and 20;
- t is 0 or 1;
- y is 0 or 1;
- p ranges from 1 to 15;
- G is a group represented by formula (III):
- wherein
- B is an alkyl containing 1-4 carbon atoms or a benzyl group,
- s is 1, 2 or 3,
- R5, X, and t are as defined above, and
- wherein the group —(CH2)s— is a spacer between the two nitrogen atoms to which it is linked.
