Abstract (en)

[origin: WO9927015A1] A halogen-free and fire resistant thermoplastic composition is produced by preparing a blend comprising a halogen-free thermoplastic material containing both, cross-linkable and non-cross-linkable compounds, a fire resistant inorganic filler, a compatibilizing agent for said inorganic filler, and a radical generating agent; the blend is mixed and dynamically cured at a temperature above the decomposition temperature of said radical generating agent to obtain a partially cross-linked thermoplastic composition and a grafting of the compatibilizing agent on all the bulk of thermoplastic material.
