extent of grafting meaning in English
接枝度
Examples
- 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含量低于10时，接枝效率可以保持在80以上； aa含量太多时易产生自聚，使接枝效率大幅度下降。 - 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
然后用十八烷基季胺盐处理过的钠基蒙脱土( mmt )分别与hdpe以及hdpe - g - aa熔融插层后制备了两种复合材料。 - 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的熔融温度和结晶度，这主要是因为剥离后的mmt在一定范围内限制了pe链的运动，从而降低了基体的结晶能力。 - 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
接着用十八烷基季胺盐处理过的钠基蒙脱土分别与hdpe以及两种hdpe一物h151熔融插层后制备了三种复合材料，研究了mmt和ydh151间的相互作用对分散和性能的影响。 - 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中只加过氧化二异丙苯( dcp )时，由于发生交联反应而使平衡扭矩明显增加，熔点和结晶度降低，加入aa后， aa与hdpe的接枝和hdpe自身的交联并存，前者对后者有抑制作用，从而使扭矩下降，熔点和结晶度部分恢复。
