Polymers types of bonds
WebPolymer types. There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength. WebMar 5, 2024 · Thermosetting polymers normally are made from relatively low-molecular-weight, usually semifluid substances, which when heated in a mold become highly cross …

WebThere are three categories of polymers: polysaccharides, polypeptides, and polynucleotides. Condensation is a reaction during which covalent bonds form between monomers that join to form polymers. Covalent bonds that form between various monomers during condensation are glycosidic, peptide, and phosphodiester bonds. WebIonic bonding is associated with ceramics, covalent bonding is associated with polymers, metallic bonding is associated with metals, and van der Waals bonding is associated with molecular solids. As we study materials in further detail in this course we will utilize these associations to explain observed materials properties in the different materials …
