ABSTRACT:
Polyolefinic fibres and films are made flame-resistant by the addition of a flame-resistant additive made up of a copolyester containing units deriving from: a) terephthalic acid; b) alkylenic glycol (C.sub.2 --C.sub.6) ; and c) phenyl hydroxymethylene phosphinic acid.
These fibres and films are prepared by the transformation into its molten state of a mixture of polyolefin and flame-resistant additive.
