Computer simulation is employed to study the structure of a thin PP film in vacuum.

用计算机模拟的方法详细研究了聚丙烯薄膜表面分子级别的结构。

In a PP/ epoxy blend, CB preferentially located in the epoxy phase which possessed higher polarity and lower melt viscosity, forming strong epoxy/ CB interaction. The cross-linking decreased the degree of crystallinity and the temperature sensibility of melt viscosity.

结果表明，在共混物中，炭黑优先分布在具有高极性、低熔融黏度的环氧树脂相中，形成较强的相互作用。由流变曲线看出，交联降低了PP熔融黏度对温度的敏感性；
