Abstract
This invention discloses a novel class of polymeric diphenylamine compounds. The compounds are produced by reacting diphenylamine with a dialkylalkenylbenzene or dihydroxyalkylbenzene having either meta or para orientation in the presence of an acid catalyst.
Claims11
A polymeric reaction product of diphenylamine and an addititonal component comprising one or more meta or para substituted compounds of the structure:
- ##STR9## wherein Y is the ##STR10## and R is an alkyl radical of from 1 to 8 carbon atoms.
A process for making a polymeric compound comprising:
- contacting diphenylamine with a second reactant and an acid catalyst, said second reactant comprising one or more compounds having the structural formula:
- ##STR14## wherein Y is para or meta substituted and is ##STR15## and R is an alkyl radical of from 1 to 8 carbon atoms.
