Glass fibres for the reinforcement of polyolefins and reinforced polyolefin compositions obtained therefrom.

摘要

Glass fibres for the production of reinforced polymers, characterized in that said fibres have a coating comprising, besides a film forming agent of polyolefinic kind and a silane, also a bis-maleamic acid such as N.N min -hexamethylene-bis-maleamic acid, N.N min -dodecamethylene-bis-maleamic acid or N.N min -isophoron-bis-maleamic acid.
<??>The invention also concerns blends consisting of 50-90% by weight of a crystalline polyolefin (e,g, polypropylene) and 50-10% by weight of glass fibres coated as indicated above.
