Polymers chapter pdf
WebJun 5, 2012 · It is the purpose of this book to describe and, when possible, to explain this wide diversity of properties. The book is concerned primarily with synthetic polymers, i.e. materials produced by the chemical industry, rather than with biopolymers, which are polymers produced by living systems and are often used with little or no modification. Type. Webmechanical properties of polymers and their measurement can be found in Chapter 21. 1.1.3.2 Rheological Properties Thermoplastics are pro-cessed and shaped in the molten state. This can be loosely defined as a state in which a polymer flows under the action of heat and pressure. Molten polymers are non-Newtonian
