impact modifier 中文意思是什麼
impact modifier
解釋
抗沖改性劑-
Preparation of polymer composites is one of the important methods to realize high performance of polymer materials. in this paper, a newly developed ethylene - octene copolymer ( eoc ), catalyzed by metallocene catalysts, was used as an impact modifier for pp instead of traditional modifier ( epdm ). the relationship between the structure and properties of polypropylene composites toughened and reinforced by eoc and cacos respectively or together was studied systematically
聚合物復合材料的制備是實現高性能聚合物材料的重要途徑之一，本論文採用茂金屬催化劑合成的新型聚烯烴彈性體乙烯-辛烯共聚物（ eoc ）代替傳統的三元乙丙橡膠，對eoc和caco _ 3兩種增韌劑分別和協同增韌增強聚丙烯復合材料體系的形態結構與性能的關系進行了系統的研究，圍繞高性能、應用探索和理論研究三個方面作了較為深入的探索和分析，獲取了很多有價值的信息，為高性能聚丙烯復合材料的開發和應用作了理論鋪墊，主要結果如下： 1 -
