EXPERIMENTAL
Reagents
ODOPB was prepared in our laboratory.26 Epichlorohydrin (EPI) from Janssen Co.and potassium hydroxide from Showa Co.were used as received.All solvents were reagent grade or were purified by standard methods before use.The diglycidyl ether of bisphenol-A [Bis-A epoxy resin,epoxy equivalent weight (EEW) 5 189] was obtained from Chang Chun Plastic Co.(Taiwan).4,49-Diaminodiphenylsulfone (DDS) and dicyandiamide (DICY) used as curing agents were from Aldrich and used as received.A phenol-formaldehyde novolac resin (Ph Nov) with an average hydroxyl functionality of 6 and a hydroxy equivalent weight of about 104 (Schenectady Chemical,HRJ-2210) was also used as a curing agent.The A-1 catalyst was (ethyl) triphenyl phosphonium acetate acetic complex; Ph3P was triphenylphosphine,which was used as curing accelerator.
Instrumental
Infrared spectra (IR) were obtained using a Nicolet 550 Fourier Transfer Infrared Spectrophotometer.Mass spectra were recorded by a VG 70-250s gas chromatography/mass spectroscopy.Differential scanning calorimetry (DSC) data were obtained in a nitrogen atmosphere at a 20°C min21 heating rate using a Perkin-Elmer DSC7 differential scanning calorimeter.Thermal gravimetric analysis (TGA) was employed with a Perkin-Elmer TGA7 at a heating rate of 20°C min21 in nitrogen or air atmosphere.Limiting oxygen index (LOI) values were measured on an ATLAS limiting oxygen index chamber .The percentage of O2 in the O2–N2 mixture just sufficient to sustain the flame was taken as the LOI.EEW of DOPO epoxy resin was determined by the HClO4/ potentiometric titration method.

我想只能是这个较果了
实验性
试剂
ODOPB 准备了在我们的laboratory.26 里氯环氧丙烷(EPI) 从Janssen Co .并且氢氧化钾从Showa Co .被使用了依照被接受.所有溶剂是试剂等级或由标准方法净化了在用途之前.bisphenol-A [ Bis 环氧树脂diglycidyl 以太,环氧当量(EEW) 5 189] 被获得了从Chang 春塑料Co .(台湾) .4,49-Diaminodiphenylsulfone (二氨基二苯基砜) 并且dicyandiamide (DICY) 被使用如同治疗的代理从Aldrich 并且被使用依照被接受.酚甲醛novolac 树脂(酸碱度11月) 以一种平均羟基功能6 和一个羟当量大约104 (Schenectady 化学制品,HRJ-2210) 并且被使用了作为一个治疗的代理.A-1 催化剂是(乙基) 三苯磷根醋酸盐乙酸复合体; Ph3P 是triphenylphosphine,哪些被使用了作为治疗加速器.
有助
红外光谱(IR) 被获得了使用Nicolet 550 傅立叶调动红外分光光度表.许多光谱由VG 70-250s 气相色谱记录了许多分光学.差别扫描量热计(DSC) 数据被获得了在氮气大气以20.6aC min21 加热速率使用Perkin-Elmer DSC7 差别扫描测热器.热量测定重量的分析(TGA) 被使用了与Perkin-Elmer TGA7 以20.6aC 的加热速率min21 在氮气或空气大气里.限制氧气索引(LOI) 价值被测量了在地图集限制氧气索引分庭.O2 的百分比在O2.CN2 混合物充足承受火焰被采取了作为LOI .DOPO 环氧树脂EEW 由HClO4/ 确定了 potentiometric 滴定法方法

仪器的
红外线的频谱 (IR) 被获得使用 Nicolet 550 傅立叶移动红外线的分光光度计。 块频谱 VG 70 250 年代的瓦斯之前被记录套色版/块光谱学。 差别的扫描热量测定 (DSC) 数据在氮大气中被获得在 20 ° C min21 加热比率使用 Perkin- 榆树 DSC7 差别的扫描热量计。 热的 gravimetric 分析 (TGA) 在氮或空气大气中以 20 ° C min21 的暖气率与 Perkin- 榆树 TGA7 一起雇用。 限制的氧索引 (LOI) 价值在一本地图限制的氧索引室上被测量。 O2 – N2 混合的 O2 的百分比正直的充份维持火焰被拿如 LOI。 DOPO 环氧基树脂树脂的 EEW 被 HClO4/potentiometric 滴定方法决定了。
