本研究係利用電漿活化接枝技術，將單體甲基丙烯酸環氧丙酯（GMA）接枝於耐龍6.6（PA66）分子鏈上，並將不同單體（GMA）接枝量之改質PA66利用摻合（Blending）技術，使其與聚硫化苯（PPS）充分混煉，使兩原料界面間之界面張力降低、界面黏著力增加，達到均勻混合之目的。並利用電子顯微鏡（SEM）觀察聚摻合後之材料界面間相容性變化情形，以DSC及流變儀的測試來觀察摻合物之物理性質隨相容性的變化關係。本研究發現，甲基丙烯酸環氧丙酯：GMA系統，由於環氧基與硫醇的反應性較為劇烈，所以能夠得到相容性較好的PPS與PA66之摻合系統。 The modification of PA66 is firstly activated by plasma reaction andfollowed by the grafting of GMA. Then the modified PA66 with differentGMA grafting content is characterized and blended with PPS. Theincrease of interface adhesion is observed with FESEM due to theimprovement of compatibility between PPS and PA66 from in-situreaction of epoxide and thiol groups. Such evidence is revealedfurther form DSC, rheometric analysis.
