Process for preparing polyolefin filaments having great adhesive strength for polymeric matrices, as well as for preparing reinforced matrix materials.

摘要

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<MathDetails id="matha01"><MathText><![CDATA[ <img id="ia01" file="imga0001.tif" wi="49" he="16" img-content="math" img-format="tif" inline="no" /> ]]></MathText></MathDetails>effected intermittently in several smaller dosages.

The process is particularly suited for treating super- strong polyethylene fibres, and making reinforced materials while applying as matrix a polyester, polyamide or epoxy resin.
