Abstract

The present invention relates to a composition comprising as component (A) a phosphonate oligomer or polymer of formula (I) and as component (B) an aminoether of formula (II) and as component (C ) wherein components (A), (B) and (C) are as defined.

Description

technical field [0001] The present invention relates to compositions comprising synergistic mixtures of thermoplastic polymers and specific aminoether and phosphonate oligomers, polymers or copolymers. [0002] The composition is especially useful as a flame retardant for thin gauge materials such as for polyolefin sheets and films and polyolefin fibers. Background technique [0003] Polyolefins are increasingly used in applications requiring flame retardancy. Flame retardancy is typically achieved by adding bromine or phosphorus compounds. However, bromine compounds significantly reduce the photostability of olefins and can therefore only be used for exterior applications to a very limited extent. [0004] Phosphorus-containing flame retardants need to be used in large quantities and are often ineffective in thin gauge applications such as fibers and sheets and films. [0005] US-A-6,599,963 describes polymer substrates comprising a flame retardant system comprising a st...
