WebJan 1, 2024 · Linear polymers consist of long flexible single chains in which the monomers are connected end-to-end by covalent bonds. Adjacent chains are joined together by van der Waals forces and hydrogen bonding. These intermolecular forces are relatively weak and determine the ability of linear polymers to soften or melt upon heating, defining the so … Webpolymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or …

Web1. Introduction Polymers were considered to be electrical insulators before the invention of conducting polymers (conjugate polymers), but these organic polymers have unique electrical and optical properties similar to those of inorganic semiconductors. 1 A conjugated carbon chain consists of alternating single and double bonds, where the highly …
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. rawlings insurance servicesWebA polymer is an organic material and the backbone of every organic material is a chain of carbon atoms.
