Abstract
Polymeric phenolic benzylic ether compositions are obtained by an intermolecular redox reaction thermolysis of tetraalkyldiphenoquinones at a minimum of about 150.degree. C. The compositions are useful as non-volatile oxidation inhibitors in polymers at high temperatures, as polymerization inhibitors for vinyl monomers, and as crosslinking co-monomers for epoxy and polycarbonate resins.
