高密度聚乙烯接枝马来酸苷对聚碳酸酯增韧

Transparent Polycarbonate Toughed by HDPE-g-MAH

为了进一步提升透明聚碳酸酯(PC)材料的应用性能,本文系统的研究了高密度聚乙烯接枝马来酸苷(HDPE-gMAH)增韧体系对透明聚碳酸酯材料的加工性能、物理力学性能以及光学性能的影响。试验结果表明,高密度聚乙烯接枝马来酸苷(HDPE-g-MAH)可以在材料对材料透明性影响不大的情况下,有效提高透明聚碳酸酯材料的韧性,当其含量低于0.3%时材料具有较好的透明性和抗冲击韧性。

In ordering to enhance the application properties of the polycarbonate,the toughening effects of HDPE-g-MAH on polycarbonate composite were studied,by the comparison of MRF,mechanical properties and optical properties. A good balance between application properties and mechanical properties could be obtained by 0. 3% load of HDPE-g-MAH.
