| 摘要 |
Glass fibers for the production of reinforced polymers, characterized in that said fibers have a coating comprising, besides a film forming agent of polyolefinic kind and a silane, also a bis-maleamic acid such as N,N'-hexamethylene-bis-maleamic acid, N,N'-dodecamethylene-bis-maleamic acid or N,N'-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 said coated glass fibers.
