ABSTRACT:
The adhesive strength of highly oriented, highmolecular polyolefin filaments for polar polymeric matrices is improved by subjecting the filaments to a corona treatment with a total irradiation dosage of ##EQU1## effected intermittently in several smaller dosages. The process is particularly suited for treating superstrong polyethylene fibers, and making reinforced materials while applying as matrix a polyester, polyamide or epoxy resin.
