Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.Step-growth polymerization refers to a type of polymerization mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers and eventually long chain polymers. Many naturally occurring and some synthetic polymers are produced by step-growth polymerization, e.g. polyesters, polyamides, polyurethanes, etc. Due to the nature of the polymerization mechanism, a high extent of reaction is required to achieve high molecular weight. The easiest way to visualize the mechanism of a step-growth polymerization is a group of people reaching out to hold their hands to form a human chain each person has two hands. There also is the possibility to have more than two reactive sites on a monomer: In this case branched polymers are produced.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! Vectran is a manufactured fibre, spun from a liquid crystal polymer created by Celanese Acetate LLC and now manufactured by Kuraray Co., Ltd. Chemically it is an aromatic polyester. These fibres are noted for thermal stability at high temperatures, high strength and modulus, low creep, and good chemical stability. They are moisture resistant and are generally stable in hostile environments. They have gold color. They are often used in combination with some polyester as a coating around Vectran core; polyurethane coating can improve abrasion resistance and act as a water barrier. Vectran has melting point of 330 °C, with progressive strength loss from 220 °C. As it has high resistance to ultraviolet radiation, it can be used outside for long term, if inspected regularly.…

Liquid-crystalpolymers are a class of aromatic polyester polymers. They are extremelyunreactive and inert, and highly resistant to fire. Liquid crystallinityin polymers may occur either by dissolving a polymer in a solvent or byheating a polymer above its glass or melting transition point.…
