中文拼音 [jiēzhīzhāiliàn]
接枝側鏈
英文
graft side chain-
For chitosan, when the concentration of chitosan is under 0. 1mg / ml, the structure of molecular chain can be observed by afm. at the same time, the refined structure of lyotropic liquid crystal of chitosan and the changes of structure were studied. films with liquid crystalline texture can be prepared from diluted solutions which concentration is lower than critical concentration of liquid crystal
對于殼聚糖( chitosan ) ,通過afm直接對殼聚糖進行分子結構水平的觀察研究,發現在濃度低於0 . 1mg ml的稀溶液中用afm可以清楚觀察到糖鏈間形成的環狀或螺旋結構,以及鏈內側枝繞合排列的樹枝狀結構,這種現象是由於糖鏈間和糖鏈內的氫鍵締合所致。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。When the graft ratio was high, the hydrophilic side chain was long and the molecular mass of the main chain of the hydrophilic matrix was great, the diffusion of pp - g - peg in pp blends would be poor, and the diffusion coefficient would also be small
接枝率越高、親水性側鏈的長度越長,親基體主鏈摩爾質量越大,接枝共聚物在聚丙烯共混體系中的遷移擴散性能越差,擴散系數越小。
