Abstract:
A composition of matter comprising:a) an aloyl urea represented by the formula ##STR1## where R.sub.1 is hydrogen or a (C.sub.1 -C.sub.50) linear or branched aliphatic, alkenyl, alkynyl, or aryl hydrocarbon; andb) an aroyl urea represented by the formula ##STR2## where R.sub.1 is a (C.sub.1 -C.sub.50) linear or branched aliphatic, alkenyl, alkynyl or aryl hydrocarbon; and Z is a heteroatom selected from the group consisting of Group IVa, Group Va and Group VIa materials of the periodic table.
