Fourier transform infrared (FTIR) spectroscopy is used to determine the cure rate of an epoxy resin consisting of Tetraglycidyl-4,4-diaminodiphenyl methane (TGDDM) and diaminodiphenylsulfone (DDS). Cure rates at 120 and 160掳C are shown to increase noticeably when 1% BF3-MEA is added to ...
不同于甲醇,如果将DGF/MBCA在一系列其他有机溶剂和酸性或碱性水环境中浸泡1周,仍能稳定存在,证实了其具有良好的稳定性(Fig. 2G,H)。 Fig. 2. Investigation of the methanolysis behavior of synthesized epoxy resin materials, and c...
A new nitrogen-containing epoxy resin (XT resin) was synthesized from chain extension of xylenephenolformaldehyde resin (XPF) and triglycidyl isocyanurate ... HZ Xing,MW Hong,QM Yu,... - 《中国化学快报(英文版)》 被引量: 40发表: 2005年 DSC and FTIR Analyses of The Curing Behavior of Epo...
epoxy resin [ə′päk·sē ′rez·ən] (organic chemistry) A polyether resin formed originally by the polymerization of bisphenol A and epichlorohydrin, having high strength, and low shrinkage during curing; used as a coating, adhesive, casting, or foam. ...

FTIR-ATR spectroscopy has been used to investigate the interdiffusion of acrylic or alkyd-based polymer coatings with an epoxy resin underlayer. It has been shown that there is considerable penetration on a short (hours) time scale and that strong hydrogen-bonding interactions occur between top coat...
3) branched polyether epoxy resin 支化聚醚型环氧树脂 1. A novelbranched polyether epoxy resinwas synthesiz ed via a end-group modification method. 通过端基转换的方法合成了一种新型支化聚醚型环氧树脂 ,通过FTIR证实了环氧基团的存在 ,用化学分析法测定了环氧值。
(PBA)as soft segments respectively.The structure and properties of the samples with different soft segments were investigated by FTIR,DMA and AFM.The results revealed that the LIPN had formed and with no chemical bond between PU and EP.PU and EP had higher interpenetrating properties in LIPN ...
The structure of VFD was characterized by Fourier transform infrared (FTIR) spectra and nuclear magnetic resonance (NMR). The addition of VFD accelerated the crosslinking reaction of epoxy system and improved the flame retardance of EP. With VFD content was 7.5 wt% (only 0.52 wt% phosphorus ...
The synthesized epoxy resin were characterized by measurement of physical properties like epoxy equivalent, viscosity, hydroxyl value, saponification value, acid value, etc., and spectroscopic techniques like FTIR and 1H NMR. High thermostability with initial decompositions temperature of 225鈥 265掳C ...
