extent of grafting 中文意思是什麼
extent of grafting
解釋
接枝度-
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。 -
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。 -
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。 -
The extent of grafting was analyzed by ftir and element analysis and thermal properties of hdpe - g - ydh151 were studied by dsc measurement. when adding dcp to hdpe, the melting temperature and the degree of crystallization of the matrix decreased because of the crosslinking reaction of hdpe
而且mmt的加入，降低了hdpe - g - aa的熔融溫度和結晶度，這主要是因為剝離后的mmt在一定范圍內限制了pe鏈的運動，從而降低了基體的結晶能力。 -
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。
