Physical properties of polymers include molecular weight, molar volume, density, degree of polymerization, crystallinity of material, and so on. Some of these are discussed herewith in the following sections.
The intensive property is given by the specific heat c , which is the heat capacity or thermal capacity per unit of mass (J·kg−1·K−1) or the molar heat capacity (J·mol−1·K−1). The heat capacity of a material is thus its ability to store or release heat energy.
Molar mass: Depends on the degree of polymerization; Density: 1.38 g/cm 3; Melting point: 260°C (500°F) Properties. PET possesses several desirable properties that make it a preferred material in numerous applications. Some of these key characteristics include:
properties (i.e. PMPs) • Express how PMPs co-vary with system composition ex. Gibbs-Duhem for Gibbs free energy. P • Euler: G 0 = k µ k n k P • chain rule: dG 0 = k (µ k dn k + n k dµ k) 2 •
13 lis 2022 · Aside from their high molar masses, how do synthetic polymers differ from ordinary molecular solids? Polymers can be classified according to their chemical composition, their physical properties, and their general application.
