Abstract
The present invention relates to a compound of the formula ##STR1## wherein n is an integer from 1 to 4, R is selected from the group consisting of hydrogen and methyl; wherein when n is 1, R.sup.1 is selected from the group consisting of alkyl radicals having 1 to 18 carbon atoms, aryl radicals having 6 to 12 carbon atoms, aralkyl radicals having 7 to 12 carbon atoms, cycloalkyl radicals having 5 to 12 carbon atoms and radicals of the formula: ##STR2## wherein x is an integer of from 1 to 7; wherein when n is 2, R.sup.1 is selected from the group consisting of alkylene radicals having 2 to 18 carbon atoms, cycloalkylene radicals having 5 to 12 carbon atoms, arylene radicals having 6 to 12 carbon atoms, ##STR3## polyalkyl glycol ether radicals having the following structure ##STR4## wherein x is an integer from 1 to 7.

A compound of the formula ##STR18## wherein n is 2, R is selected from the group consisting of hydrogen and methyl;
- R.sup.1 is selected from the group consisting of alkylene radicals having 2 to 18 carbon atoms, cycloalkylene radicals having 5 to 12 carbon atoms, arylene radicals having 6 to 12 carbon atoms, ##STR19## polyalkyl glycol ether radicals having the following structure ##STR20## wherein x is an integer from 1 to 7, a thioether radical having the following structure
- --CH.sub.2 --CH.sub.2 --S--CH.sub.2 --CH.sub.2 --;
- R.sup.2 is an alkylene radical selected from the group consisting of 6 and 9 carbon atoms;
- R.sup.3 is an alkyl radical selected from the group consisting of 1 and 4 carbon atoms;
- with the proviso that the total sum of the number of carbon atoms for R.sup.2 and R.sup.3 equal 10.
