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;
