Some of the common examples of linear polymers are polyethylene, PVC, polystyrene, and polyamides. Linear polymers are generally more rigid. E. Frixione, M. Hernández, in Comprehensive Biotechnology (Second Edition), 2011.
21 gru 2017 · Some Examples of Linear Polymers. Teflon; Polypropylene; Polystyrene; Linear polymers are often semi-crystalline or crystalline; since there are no branches, the polymer chains can tightly pack. Hence the density is high.
Common examples of linear polymers include high-density polyethylene (HDPE), polyvinyl chloride (PVC), and polypropylene (PP). Branched Polymers. Branched polymers have side chains or branches stemming from the main polymer backbone. These branches can emerge at various points along the chain, creating a more complex and interconnected structure.
Linear polymers resemble ‘spaghetti’ with long chains. The long chains are typically held together by the weaker van der Waals or hydrogen bonding. Since these bonding types are relatively easy to break with heat, linear polymers are typically thermoplastic.
Unlike branched or crosslinked polymers, linear polymers exhibit different melting points and solubility behaviors due to their structural simplicity. Common examples of linear polymers include polyethylene and polystyrene, which have widespread applications in packaging and consumer products.
In the case where polymer chains have linear backbones, there is strong covalent bonding that exists along the length of the backbones. Polyvinyls and polyesters are commercial polymers with such linear backbones. Polyvinyl chloride, polystyrene and polyethylene are examples of the polyvinyl family.
Common examples of linear polymers include polyethylene and polypropylene, widely used in packaging and consumer goods. Linear polymers generally exhibit lower melting points compared to branched or cross-linked counterparts due to their less complex structures.
