摘要：The thermal properties of PA66/PC/silicone rubber composites prepared by dynamic vulcanization were investigated. By adding silicone rubber as a toughener, engineering plastics with outstanding thermal properties were prepared via reactive extrusion. The PA66/PC/silicone rubber composites show very good retention of impact strength and higher hardness even after heat aging. The average degradation and softening temperatures of the composites are higher than that of other common engineering plastics that we mainly attribute to the introduction of the dynamically vulcanized silicone rubber and the forming of a net-like structure in the PA66/PC matrix. The addition of montmorillonite improved the hardness and the degradation temperature of the composites. Copyright ? Taylor & Francis Group, LLC.
