Abstract
A low molecular weight complex of a lactam and a substituted phenolic compound having the formula ##SPC1## Wherein n is an integer of 3 to 5; W is hydrogen or alkyl having from 1 to 8 carbon atoms including cycloalkyl substituents; each R and R', R.sub.2 and R'.sub.2 is alkoxy of from 1 to 3 carbon atoms, nitro, cyano, hydrogen, halogen or alkyl having from 1 to 12 carbon atoms and at least one R, R', R.sub.2 and R'.sub.2 is a substituent other than hydrogen, and wherein R.sub.2 and R'.sub.2 can also be alaninyl.
