Flammfeste Polyolefinfasern und Folien

摘要

Disclosed are polyolefinic fibres and films which have been made flame-resistant by the addition of a flame-proofing additive, i.e., a copolyester containing units deriving from (a) terephthalic acid; (b) (C2-C6) alkylene glycol; and (c) phenyl hydroxymethylene phosphinic acid. These fibres and films are prepared by the transformation of a mixture of polyolefin and additive in the molten state and extrusion of said melt.
