    • In accordance with the present invention, we have developed compositions useful for the preparation of prepregs, laminates, and the like having excellent performance properties. Invention compositions comprise a combination of a first component ( i.e. , a low loss, low dielectric constant, hydrocarbyl thermoplastic resin), a second component ( i.e. , a component which is capable of crosslinking to produce a thermoset in the presence of the first component), a free radical source, and optionally, one or more additives and/or diluents. Invention compositions can be prepared from widely available and inexpensive starting materials. As a result, invention compositions not only provide fabricated articles having outstanding performance properties, in addition, the cost of producing the resulting articles compares quite favorably with the cost of making competitive materials which require the use of more expensive, less readily available starting materials. Also provided in accordance with the present invention are prepregs prepared from invention compositions, laminated sheets prepared from the above-described prepregs, printed wiring boards, methods of making each of the above, and the like.
    • 根据本发明,我们开发了可用于制备具有优异性能的预浸料,层压板等的组合物。 本发明组合物包括第一组分(即,低损失,低介电常数,烃基热塑性树脂),第二组分(即,在第一组分存在下能够交联以产生热固性的组分)的组合, ,自由基源和任选的一种或多种添加剂和/或稀释剂。 本发明组合物可以由广泛可得的和廉价的原料制备。 结果,本发明组合物不仅提供具有突出性能的制品,此外,生产所得制品的成本与制造需要使用更昂贵,不太容易获得的起始材料的竞争性材料的成本相当有利。 根据本发明还提供了由本发明组合物制备的预浸料,由上述预浸料制备的层压片,印刷线路板,制备上述各种方法等。
