  under CWC schedule 2.B.4. Mass spectrometric studies revealed some fragmentation pathways, such as elimination of alkyl(oxo)phosphane oxide (RPO2), chlorine, chloromethylene, alkene, HCl, and H2O, α-cleavage and McLafferty-type and hydrogen rearrangements. The proposed fragmentation processes include some new fragmentation patterns, such as isomerization of cations to stabilized carbocations and oxocarbocations

  摘要 质谱图的可用性和解释技能对于明确识别与化学武器公约 (CWC) 相关的化合物至关重要。本文研究了螺烷基膦酸酯 I 和 5,5-双(氯甲基)-2-烷基-1,3,2-二氧膦烷 2-氧化物 II 作为化合物的电子电离 (EI) 和电喷雾电离 (ESI) 质谱裂解路线包含在 CWC 附表 2.B.4 中。质谱研究揭示了一些碎裂途径，例如消除烷基（氧）氧化膦 (RPO2)、氯、氯亚甲基、烯烃、HCl 和 H2O、α-裂解和 McLafferty 型以及氢重排。提议的裂解过程包括一些新的裂解模式，例如将阳离子异构化为稳定的碳正离子和氧代碳正离子，通过协同逆向[2+2]环加成反应和1,2PO烷基转移消除甲醛和烷氧基。使用 EI-MS 和 MS/MS 分析氘代类似物来确认碎片的结构。研究结果将为禁止化学武器组织（OPCW）中央分析数据库（OCAD）做出贡献，该数据库可用于在现场检查和 OPCW 能力测试期间检测和识别

  It is an object of the present invention to provide a styrene type resin composition excellent in thermal stability, hue, fluidity, and heat resistance, and also having the flame retardant performance, and a molded product excellent in outward appearance, formed therefrom. The present invention provides a flame retardant styrene type resin composition comprising (A) a styrene type resin (component A) in an amount of 100 parts by weight, (B) a polyphenylene ether type resin (component B) in an amount of 0 to 100 parts by weight, and (C) an organophosphorus compound (component C) represented by the following formula (1) in an amount of 1 to 100 parts by weight, characterized in that the organophosphorus compound (component C) satisfies: (i) the weight loss residue on heating at 500° C. is 10% or less; (ii) the HPLC purity is 90% or more, and (iii) the acid value is 0.5 mg KOH/g or less (where in the formula, Ar 1 and Ar 2 may be the same or different, and is a phenyl group which may have a substituent.)

  The present invention exploits reactive organophosphorus compounds containing unsaturated vinyl groups, which can be used in a flexible and highly controlled manner to prepare various macromolecular derivatives either via radical reactions or via Michael addition with suitable nucleophiles. Based on the fact that secondary amine groups on the one hand and vinyl groups on the other hand can work as mutual linking sites, an arsenal of novel and useful addition products can be built up. By selecting the number of secondary amine sites and vinyl sites of the participating reaction partners, very different addition products can be formed. In particular, one can form either linear chain type macromolecules (i.e. linear oligomers or polymers) or highly crosslinked network polymers.
