Abstract: The e.s.r. spectrum of acrylic acid, irradiated in the presence of polyethylene at 77 K, differs considerably from that previously found at room temperature. The major components, ascribed to ionic species, are only observed when both acrylic acid and polyethylene are present simultaneously. It is known that under these conditions a sensitized crosslinking occurs, and this is ascribed to a novel ion-radical chain reaction, involving the interaction of the growing poly (aery lie acid) chain end radical with cations formed on the base polyethylene.
