Abstract
A compound of the formula ##STR1## in which R.sup.1 and R.sup.2 taken together, and R.sup.3 and R.sup.4 taken together, independently represent a polymethylene chain leaving 3 or 4 carbon atoms, or a polymethylene chain having 3 or 4 carbon atoms substituted by at least one lower alkyl radical having from 1 to 4 carbon atoms and R.sup.5 to R.sup.8 are independently hydrogen, hydrocarbyl or substituted hydrocarbyl. Typically R.sup.1 and R.sup.2 and also R.sup.3 and R.sup.4 complete a trimethylene ring, R.sup.5 and R.sup.7 are each hydrogen and R.sup.6 and R.sup.8 are alkyl such as methyl.
