  1. As to the high - density polyethylene, two strategies were performed : ( 1 ) after being modified by grafting polar groups on its backbone, polyethylene and organic montmorillonite were melt mixed directly, which could obtain the polyethylene / montmorillonite nanocomposites. the effect of groups grafted on the backbone on the efficiency of intercalation was investigated in this paper ; ( 2 ) choosing the grafters obtained in this experiment as the compatilizers, polyethylene / montmorillonite nanocomposites had also been prepared by melt mixing the polyethylene, grafter and organic montmorillonite. the difference of grafters and sequence of mixing on the intercalation result had also been analyzed

    對于高密度聚乙烯，採用以下兩種思路進行： （ 1 ）對聚乙烯首先進行功能化改性，使聚乙烯分子鏈上接枝上不同的極性基團，將改性后的聚乙烯再同有機蒙脫土直接熔融復合，成功的制備了聚乙烯蒙脫土納米復合材料，並考察了接枝到聚乙烯主鏈上基團的不同對最終插層效果的影響； （ 2 ）選用制得的接枝物作為相容劑，將聚乙烯，接枝物，有機蒙脫土三者熔融復合，也可以得到聚乙烯蒙脫土納米復合材料，並對選用不同的接枝物作為相容劑以及復合順序對最終插層效果的影響加以分析。
  2. With increasing the content of ydh151, the grafting degree increased and the grafting efficiency decreased. however, the content of dcp cannot be added too much so as to avoid the crosslinking reaction between ydh151 and hdpe

    但是由於ydh151與hdpe也會發生交聯，所以dcp的量不能過多， ydh151的量也在低於10 %為宜， ydh151含量太多時接枝效率大幅度一卜降。
  3. The grafting degree and grafting efficiency were decreased. the conversion of semi - contionious emulsion polymerization was decreased as the addition of mmt was increased because of the effect of monomer diffusion and decreasing efficiency of intiating agent

    半連續乳液聚合法制備abs mmt時，蒙脫土的存在使聚合轉化率顯著下降，並且mmt粘土含量越高，對乳液共聚合造成的不利影響越大。
  4. Preparation, structure and properties of hdpe ~ g ~ aa / mmt nanocomposites melt grafting reaction of hdpe with aa was performed in thermohaake rheomix and hdpe - g - aa with high grafting degree and high grafting efficiency was prepared. the change of torque indicated that the graft copolymerization was existed during melt compounding. the extent of grafting was analyzed by ftir and element analysis

    在hdpe中只加過氧化二異丙苯（ dcp ）時，由於發生交聯反應而使平衡扭矩明顯增加，熔點和結晶度降低，加入aa后， aa與hdpe的接枝和hdpe自身的交聯並存，前者對後者有抑制作用，從而使扭矩下降，熔點和結晶度部分恢復。
  5. However, when aa content exceeded 10wt. - %, the increment of the extent of grafting level off and the grafting efficiency decreased remarkably. afterward hdpe - g - aa / mmt composites and hdpe / mmt composites were prepared via melt compounding

    然後用十八烷基季胺鹽處理過的鈉基蒙脫土（ mmt ）分別與hdpe以及hdpe - g - aa熔融插層后制備了兩種復合材料。
  6. This article confirmed the grafting efficiency of starch grafted to acrylic acid and the structure of starch and its grafted matter through the separation, purification and analysis tests to the grafted copolymer and the grafted forked - chain matter produced from the process of this reaction ; and deduced the formula of the velocity of such reaction mentioned above with a calculated result of the apparent activation energy in this reaction by the curve showing the relationship among the consistency of starch, monomer and initiator and the velocity of the grafting copolymerization

    摘要對澱粉接枝丙烯酸所得接枝共聚物及接枝側鏈物進行分離提純和分析測試，確定了其接枝效率並表徵了澱粉及其接枝物的形態結構；通過分別測定接枝共聚反應速率與澱粉、單體、引發劑濃度的關系曲線，確定了該接枝共聚反應的速率關系式；推算出了反應的表觀活化能。
  7. Efficiency of grafting

    接枝效率
  8. When aa content was less than 10wt - %, the extent of grafting increased with increasing the content of aa, and the grafting efficiency maintained in a high level of about 80 %

    在aa含量低於10時，接枝效率可以保持在80以上； aa含量太多時易產生自聚，使接枝效率大幅度下降。
  9. Moreover when aa content exceeded 10wt. - %, the increment of the extent of grafting level off and the grafting efficiency decreased remarkably. then hdpe - g - ydh151 / mmt composites and hdpe / mmt composites were prepared via melt compounding. ftir proved that there were interactions between ydh151 and mmt sheets

    接著用十八烷基季胺鹽處理過的鈉基蒙脫土分別與hdpe以及兩種hdpe一物h151熔融插層后制備了三種復合材料，研究了mmt和ydh151間的相互作用對分散和性能的影響。
