السلام عليكم اخوان احتاج الي بعض التفسيرات العلميه لكل من
1- ايهما اكبر مورونة البولي اثيلين عالي الكثافة ام البولي اثيلين واطيء الكثافة؟ 2- هل ان البولي اثيلين واطيء الكثافة يتحمل مقاومة صدمة اكثر من البولي اثلين عالي الكثافة ؟ولماذا.وهل تزداد مقاومة الصدمة عند رفع درجة الحرارة المختبر ؟ ارجو ارسالى الرد مع التفسير العلى لكل حالة

Synthetic Methods in Step-Growth Polymers  Synthetic Methods in Step-Growth Polymers By: Martin E. Rogers(Editor), Timothy E. Long(Editor) ISBN-10: 047138769X ISBN-13: 9780471387695 Publisher: Wiley-Interscience - 2003-05-01 Hardcover | 605 Pages Editorial Review: This reference volume provides a concise source of information on synthetic techniques, purification, and characterization methods for step-growth polymers and also addresses future synthetic trends. This applications-oriented handbook is a one-stop, at-your-fingertips source of information for researchers, technologists, and industrial managers. Encompassing a single reference of the classical and state-of-the-art synthetic techniques for preparing polymers via step-growth polymerization, this text provides a historical background of step-growth polymerization, baic informathion regarding major classes of step-growth polymers, and experimental techniques such as purification, synthesis, and characterization. Coverage includes: - Polyurethanes and Polyureas - Polyimides and Other High-Temperature Polymers - Non-Traditional Step-Growth Polymerizations—ADMET - Non-Traditional Step-Growth Polymerization—Transition Metal Coupling - Depolymerization and Recycling All chapters are contributed by leading experts in their respective fields. Chemists, chemical engineers, and materials scientitsts, as well as industrial, academic, and government libraries, will find Synthetic Methods in Step-Growth Polymers to be an unparalleled resource for this category of polymerization. المحتوى *******s 1.

Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers  Book Description: The versatility of the emulsion copolymerization reaction and the ability to control the properties of the final latices have led to rapid expansion both in the quantity of polyvinylacetate and vinyl acetate-acrylic copolymer latices and in their applications. Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers provides a collection and logical organization of the published data - much of it formerly found fragmented throughout various journals and little of it referenced in general emulsion polymerization books. To date, no one source has offered chemists and polymer, surface, or colloid specialists the "big picture" of polyvinylacetate-based latices. Integrating established knowledge with the latest research developments, this book provides the background for understanding the mechanism and kinetics of emulsion polymerization initiated in the aqueous phase and some of the practical problems of latex production. The author presents an overview of industrial practices, new applications, and all of the fundamental material - avoiding theoretical controversies. With in-depth discussion of the ingredients found in most industrial recipes, Vinyl Acetate Emulsion Polymerization and Copolymerization with Acrylic Monomers helps eliminate costly and time-consuming "trial and error" practices. It serves not only as an introduction for those new to the field, but also as a valuable reference for researchers and applied scientists in both industry and academia. dawinlod link http://rapidshare.com/files/22355506/VAEPaCwAM.rar
