Polymers may be naturally found in plants and animals (natural polymers) or may be man-made (synthetic polymers). Different polymers have a number of unique physical and chemical properties due to which they find usage in everyday life. JEE Main 2021 LIVE Chemistry Paper Solutions 24-Feb Shift-1 Memory-Based

change of the rheological properties of the co mpound, especially a viscosity decrease of the polymer matrix by degradation of the elastomer chains. Figure 4 gives a schematic view of the viscosity changes during mixing and the contributions of temperature increase and polymer breakdown to the viscosity decrease. Fig. 4.

Jan 19, 2022 · Physical Properties of Polymer. 1. Tensile Strength – The strength of a polymer to elongate without breaking is its tensile strength. Physical strength and durability depend on this property of polymers. 2. Melting Point and Boiling Point – Polymers have a high melting point and boiling point.

Physical properties of polymers include molecular weight, molar volume, density, degree of polymerization, crystallinity of material, and so on. Some of these are

When a polymer is deformed, the stress increases with strain. Typical stress-strain curves in tension for selected polymers are given in Figure 2. The properties of these polymers can be related to the characteristics of their stress-strain curves. Tests may be performed in shear, flexure, compression, torsion, or tension. Typical high ...
