Solid polypropylene and polyethylene may be cross-linked effectively by irradiation in the presence of a chlorobenzene, the effect of chlorobenzene being more marked with polypropylene which is normally difficult to cross-link. The form of the polymer to be irradiated may be either polymer swollen with chlorobenzene or a solution of polymer in chlorobenzene; whatever the form, it should be 50 to 8O% chlorobenzene. Dichlorobenzenes and polychlorobenzenes can also be used. The radiation should be of energy O.l to 10 Mev and used in doses from l to 50 x l0/sup 6/ rep. Several experiments were performed on polypropylene and polyethylene with several solvents and chlorobenzenes for comparison, using 0.8-Mev electrons and varying doses. The cross-linking method may also be applied to filled polymers. (D.L.C.)
