ABSTRACT:
Disclosed is a method of inhibiting the formation of scale on reactor surfaces in contact with a polymerizing vinyl monomer comprising contacting said monomer with a terpolymer which comprises the condensation reaction product of
(A) an aromatic compound that contains the group ##STR1## where Q is OR or SR and R is hydrogen, alkyl from C.sub.1 to C.sub.15, or aryl, alkaryl, or aralkyl from C.sub.6 to C.sub.15 :
(B) about 0.1 to about 10 moles of a carbonyl compound per mole of said aromatic compound; and
(C) about 0.1 to about 10 moles of a thiourea per mole of said aromatic compound.
