caprolactam polymerization 中文意思是什麼
-
In this paper, two kinds of polyazomethine / nylon - 6 ( pam / pa - 6 ) composites with different chemical structures were prepared by means of in - situ polymerization. pam1 and pam2 were prepared from the reaction of terephthalaldehyde with l, 6 - hexanediamine ( paml ), and terephthalaldehyde with 4, 4 ' - diamiediphenyl ( pam2 ). during the preparation, pam chain ends played a retard role in the polymerization of s - caprolactam obviously
本文通過原位聚合法制備了兩種不同化學結構的聚甲亞胺尼龍6 （ pam pa6 ）分子復合材料， pam1為對苯二甲醛與1 ， 6 -己二胺反應制備的聚甲亞胺， pam2為對苯二甲醛與4 ， 4 』 -二氨基二苯醚合成的聚甲亞胺。 -
Through the characterization of the molecular weights of pam, sem and dsc of composite, the results clarified the change of mechanical properties of composites. the tensile strength and impact strength of pam2 / pa - 6 composite showed that were related to the content of initiator naoh for the polymerization of e - caprolactam. the intrinsic viscosity of pam, sem and the crystallinity of nylon phase carried out the results, which explained the change of mechanical properties of composites
對于pam2 pa - 6體系，復合材料的拉伸強度與沖擊強度隨醛胺摩爾比的變化趨勢與引發劑用量有關，通過pam2分子量、尼龍結晶度、球晶形態、 sem以及dsc等表徵方法對這種變化趨勢的研究表明，復合材料的力學性能與上述因素有密切的關系。 -
Three methods of avoiding the effect of aldehyde end - group on the polymerization of e - caprolactam were compared. it was useful for the industrial application through the salting e - caprolactam monomer with the initiator naoh firstly
通過-己內酰胺單體先與引發劑氫氧化鈉成鹽的方法可以消除pam分子鏈中醛端基對基體聚合的影響，為pam pa - 6復合材料的工業化應用提供了一定的理論基礎。
