Principle Characteristics of Polymers Lecturer : ... polymers have the following general properties Polymers can be very resistant to chemicals Polymers can be both thermal and electrical insulators Generally, polymers are light in weight with varying degrees of strength Properties of Polymers . The disordered tangling of the polymer … Some of these are Barrier Properties of Polymers (Permeability, Solubility and Diffusivity) The permeability or inverse barrier is an important physical property for many industrial and biomedical applications of polymers. Flow Properties of Polymers Time-independent Fluids.
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost. The density of polymer materials is low because it mainly composed of light elements. Regular table sugar is the disaccharide sucrose (a polymer), which is composed of the monosaccharides fructose and glucose (which are monomers). POLYMERS and their PROPERTIES Introduction Basic Topics: Types of Polymers Classification of Polymers Characteristics of Polymers Properties of Polymers Streng… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Properties of Polymer Materials 1. Polymer Glass Transition In the study of polymers and their applications, it is important to understand the concept of the glass transition temperature, Tg. The following variables can be controlled when producing a polymer. As noted above, synthetic HDPE macromolecules have masses ranging from 105 to 106 amu (LDPE molecules are more than a hundred times smaller). Polymers have different properties and uses but it is difficult to dispose of them.
The reagent used to initiate the polymerization reaction. Different polymers have a number of unique physical and chemical properties due to which they find usage in everyday life. New are chapters and sub-chapters discussing extended chain polymers, liquid crystal polymers and high performance polymers, De Gennes' scaling concept of polymer solutions, physical ageing, acoustic properties, the dual-mode permeation theory, the decomposition temperature and polymer reinforcing constructions. Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost. Properties of Polymers: Their Correlation with Chemical Structure; Their Numerical Estimation and Prediction from Additive Group Contributions summarizes the latest developments regarding polymers, their properties in relation to chemical structure, and methods for estimating and predicting numerical properties from chemical structure. Synthetic polymers, which includes the large group known as plastics, came into prominence in the early twentieth century. Monomers and polymers: Many small monomer subunits combine to form this carbohydrate polymer. Polymers range from familiar synthetic plastic such as polystyrene to natural bio-polymers such as DNA and proteins that are fundamental to biological structure and function. Polymer chemistry is the study and manipulation of synthetic and organic chemical substances known as polymers.
