具体描述
During the past 30 years, the field of alkene polymerization over transition metal catalysts underwent several major changes:
1. The list of commercial heterogeneous Ziegler-Natta catalysts for the synthesis of polyethylene and stereoregular polyolefins was completely renewed affording an unprecedented degree of control over the polymer structure.
2. Research devoted to metallocene and other soluble transition-metal catalysis has vastly expanded and has shifted toward complexes of transition metals with multidentate ligands.
3. Recent developments in gel permeation chromatography, temperature-rising fractionation, and crystallization fractionation provided the first reliable information about differences between various active centers in transition-metal catalysts.
4. A rapid development of high-resolution 13C NMR spectroscopy resulted in greatly expanded understanding of the chemical and steric features of polyolefins and alkene copolymers.
These developments require a new review of all aspects of alkene polymerization reactions with transition-metal catalysts. The first chapter in the book is an introductory text for researchers who are entering the field. It describes the basic principles of polymerization reactions with transition-metal catalysts, the types of catalysts, and commercially manufactured polyolefins.
The next chapter addresses the principal issue of alkene polymerization catalysis: the existence of catalyst systems with single and multiple types of active centers. The subsequent chapters are devoted to chemistry and stereochemistry of elemental reaction steps, structures of catalyst precursors and reactions leading to the formation of active centers, kinetics of polymerization reactions, and their mechanisms.
The book describes the latest commercial polymerization catalysts for the synthesis of polyethylenes and polypropylene
The book provides a detailed description of the multi-center nature of commercial Ziegler-Natta catalysts.
The book devotes specialized chapters to the most important aspects of transition metal polymerization catalysts: the reactions leading to the formation of active centers, the chemistry and stereochemistry of elemental polymerization steps, reaction kinetics, and the polymerization mechanism.
The book contains an introductory chapter for researchers who are entering the field of polymerization catalysis. It describes the basic principles of polymerization reactions with transition-metal catalysts and the types of commercially manufactured polyolefins and copolymers
The book contains over 2000 references, the most recent up to end of 2006.
作者简介
Yury Kissin (born in 1937) received his degree in Polymer Chemistry in 1965 at Institute of Chemical Physics in Moscow investigating α-olefin polymerization reactions with heterogeneous Ziegler-Natta catalysts. Since 1960 until 1977 he worked in Institute of Chemical Physics studying kinetics of polymerization reactions of ethylene, propylene and higher α-olefins and the structure of polyolefins and catalysts by IR. He immigrated to USA in 1979 and worked as Research Associate first at Gulf Research and Development Company in Pittsburgh, PA (1980-1985), at Edison Research Center of Mobil Chemical Company in NJ (1985-2000), and at Engelhard/BASF Research Center in Iselin, NJ (2004-2008). His main research subjects were synthesis of Ziegler-Natta catalysts, kinetics of polymerization and oligomerization reactions, and spectroscopic studies of polymerization catalysts. Since 2000 he is a Visiting Scientist at Department of Chemistry of Rutgers University, NJ, where he studies kinetics of olefin polymerization reactions with Ziegler-Natta and late-period transition metal catalysts. He authored three books (Isospecific Polymerization of Olefins, Springer, 1985; Polymers and Copolymers of Higher α-Olefins, Hanser, 1997; Alkene Polymerization Reactions with Transition Metal Catalysts, Elsevier, 2008), twenty articles in chemical and polymer encyclopedias, ~210 scientific articles, and over 60 patents in the fields of synthesis of Ziegler-Natta and metallocene catalysts.

读后感
用户评价
刚翻开这本关于过渡金属催化的烯烃聚合反应的著作,立刻被其深厚的学术底蕴和严谨的逻辑结构所吸引。书中对不同类型过渡金属催化剂的**电子结构、空间构型**及其对聚合反应活性和产物微观结构调控机制的探讨,展现出作者对催化化学前沿的深刻洞察。特别是对**茂金属和非茂金属催化体系**在烯烃聚合过程中的**链增长、链转移和链终止**动力学参数的精细分析,让人仿佛置身于高精度的实验数据面前,理解了为什么特定的配体设计能催化出具有特定分子量分布和立构规整性的聚合物。书中穿插的示意图和反应机理的图示清晰明了,即便对于初涉此领域的读者,也能逐步构建起对复杂催化循环的直观认识。作者在论述中并没有止步于现象的描述,而是深入挖掘了**过渡态理论在解释催化选择性**中的应用,这种理论与实践相结合的叙述方式,极大地提升了本书的学术价值,使其不仅仅是一本工具书,更是一部启发深入思考的学术专著。其对**位阻效应和电子效应**如何共同影响催化中心活性位点几何构象的论述尤其精彩,为设计下一代高效、高选择性聚合催化剂提供了坚实的理论基础。
这本书的编排方式,说实话,非常适合那些已经有一定高分子化学基础,渴望进入**工业应用和前沿研究交叉领域**的读者。它没有过多地纠缠于基础的化学键理论,而是直接切入**实际催化剂的制备、表征及其在工业反应器中的行为模拟**。我特别欣赏其中关于**“活性中心老化”和“催化剂失活路径”**的章节,这部分内容在许多教科书中往往被一笔带过,但对于追求稳定、长周期运行的工业生产而言,却是至关重要的。作者详细列举了热力学失活、氧化失活和催化剂聚集等多种失活机制,并辅以**谱学技术(如XPS、固体核磁)**在诊断这些失活过程中的应用案例,这种实战化的内容对于科研人员具有极高的参考价值。此外,书中对于**新型共聚体系**,例如烯烃与极性单体的**催化共聚挑战**的讨论,也体现了作者紧跟时代步伐的视野,揭示了如何通过精细的配体调控来克服传统催化剂对极性官能团的敏感性,这无疑是未来高功能性聚合物开发的关键突破点之一。
如果用一个词来形容阅读这本书的感受,那一定是**“深度与广度并存”**。这本书的“深度”体现在对**量子化学计算结果**在预测催化剂性能上的应用。作者不仅仅是引用计算结果,而是详细阐述了**密度泛函理论(DFT)**是如何被用来计算催化循环中关键步骤的能垒,从而量化不同配体替换对反应活性的影响。这种方法论的展示,极大地拓宽了我们对催化剂设计范式的理解,从依赖经验试错转向基于第一性原理的理性设计。而其“广度”则体现在对**不同金属系列(从早期过渡金属到贵金属)**的聚合催化潜力的全面覆盖,即便是相对冷门的**稀土金属催化体系**,书中也给予了充分的篇幅来讨论其独特的链转移机制和聚合物性能特征。这种包罗万象的覆盖面,使得本书能够作为一本**综合性的参考手册**,在不同领域的化学家和工程师之间架起沟通的桥梁,确保读者在处理特定聚合问题时,能够迅速找到跨体系的解决方案和思路启发。
这本书的语言风格极为**克制和精准**,没有过多花哨的修饰词,每一个句子都似乎是为了承载特定的科学信息而存在。它更像是一份经过严格同行评审的、高度浓缩的科学报告合集,而非轻松的阅读材料。对于像我这样追求**机制细节**的读者来说,这种风格是极其友好的。尤其是在阐述**“活性位点异构性”**对聚合物微观结构影响的那几章,作者通过对不同催化剂批次之间NMR谱图的对比分析,清晰地描绘出**多重活性中心共存**的复杂现象。书中对**聚合反应的实时监测技术**,比如原位傅里叶变换红外光谱(In-situ FTIR)在跟踪催化剂转化和聚合物生长方面的应用案例分析,让人感到技术的前沿性。这些详实的数据和图表,帮助读者辨识出那些隐藏在宏观性能之下的微观反应细节,为解决复杂的聚合物性能偏差问题提供了强有力的诊断工具,体现了极高的科学严谨性。
坦白说,这本书的阅读体验是**充满挑战但收获巨大的**,它要求读者具备较高的化学基础,特别是对有机金属化学和高分子动力学有扎实的了解。对于那些试图通过这本书快速了解聚合反应“是什么”的人来说,可能会感到吃力,因为它更专注于解释“为什么会这样”以及“如何做得更好”。书中关于**受控/活性聚合(CRP)在烯烃体系中的实现**的讨论,是本书的一大亮点,它超越了传统自由基聚合的范畴,探讨了如何利用特定的金属络合物来实现**精确的分子量控制和拓扑结构设计**。这种对“可控性”的极致追求,体现了现代聚合化学的发展方向。书中对**新型单体和催化剂的兼容性研究**的深入剖析,特别是对**非对称催化聚合**领域的前沿探索,为读者指明了未来数年内值得投入精力攻关的研究方向。这本书无疑是为高水平的研究人员和研究生量身打造的,它推动的不是知识的普及,而是学科边界的拓宽。
