Abstract

A polymer compsn. comprises at least 80 wt.% polyolefin and 0.5-15 wt.% boric acid, anhydrous borax or aluminium borate. Pref. the polyolefin is polyethylene or an ethylene copolymer with an alpha-olefin or vinyl acetate and forms 90-97 wt.% of the compsn. The boron cpd. is present at 3-8 wt.% and the compsn. also contains an antioxidant, UV stabiliser, humidifier, antistatic agent and lubricant.
