本研究利用回收廢棄的交聯聚乙烯(Crosslinked Polyethylene，CPE)做為添加材料，超高分子量聚乙烯(UHMWPE)及聚丙烯接枝馬來酸酐(PP-g-MA)、聚乙烯接枝馬來酸酐(PE-g-MA)為基材，經由雙螺桿混煉機進行混煉後，製得一系列的複合材，透過FT-IR、X-ray、SEM、及TGA、DMA之檢測分析探討複合材之相關性質，由實驗結果顯示：CPE與UHMWPE、PP-g-MA或PE-g-MA製成之複合材，均能有效提高其耐熱性質。CPE之填加對CPE/PP-g-MA複合材之力學性能無顯著提升。但，CPE/UHMWPE複合材之儲存模量可因CPE之添加而提升，且在CPE為1%時，儲存模量有最大值，而CPE/PE-g-MA複合材之儲存模量隨交聯聚乙烯濃度之增加而逐漸升高。
CPE/PE-g-MA複合材如再行第二次交鏈有助於複合材耐熱性之提高，但如過度交鏈則對其力學性能及耐熱性反而變差。

In this research, a series of composites were made based on UHMWPE, PP-g-MA and PE-g-MA by recycling and utilizing scrap (Crosslinked Polyethylene，CPE) as addition materials after being mixed in mixing rolls with double screws. The related nature of the composites will be discussed by detecting and analyzing FT-IR, X-ray, SEM, TGA and DMA. The results show as follows:
The composites made of CPE together with UHMWPE，PP-g-MA or PE-g-MA can effectively improve its heat-resisting property. The addition of CPE brings no obvious enhancement to the mechanical property of CPE/PP-g-MA composites, yet the addition of CPE brings improvement to the storage modulus of CPE/UHMWPE composites. What’s more, when CPE is 1%, the storage modulus reaches its maximum, yet the storage modulus of CPE/PE-g-MA composites increases along with the increase of CPE concentration.
Second mixture of CPE/PE-g-MA composites will be helpful to the improvement of its heat-resistance, yet too many crosslinks will worsen its mechanical property and heat-resistance.
