Differbetween
Polymers are macromolecules that are made out of many monomers bonded to each other. ... The main difference between linear polymers and crosslinked polymers is that linear polymers are straight chain structures whereas crosslinked polymers are branched structures.

What is a crosslinked polymer?
Polymer chemistry. Crosslinking is the general term for the process of forming covalent bonds or relatively short sequences of chemical bonds to join two polymer chains together. ... When polymer chains are crosslinked, the material becomes more rigid.
Why crosslinked polymers are stronger than linear polymer?
The cross-linked polymer forms long chains, either branched or linear, that can form covalent bonds between the polymer molecules. Because cross-linked polymers form covalent bonds that are much stronger than the intermolecular forces that attract other polymer chains, the result is a stronger and more stable material.
What is linear polymer?
A linear polymer is a long continuous chain of carbon–carbon bonds with the remaining two valence bonds attached primarily to hydrogen or another relatively small hydrocarbon moiety.
What is linear and cross linked polymers explain with diagram?
The key difference between cross linked polymer and linear polymer is that the monomer units of linear polymers have end-to-end links, resembling the beads in a necklace, whereas cross linked polymers are made up of chains that are joined together by a series of covalent bonds, called cross-links.
What is definition of polymer?
Polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.
Which of the following is thermosetting polymer?
Bakelite is a cross linked polymer which after heating can't be recovered in its original structure. Hence it is a thermosetting polymer.
What are 2 structures of polymers?
In practice, some polymers might contain a mixture of the various basic structures. The four basic polymer structures are linear, branched, crosslinked, and networked. Diagrams of linear, branched, crosslinked, and networked polymer structures. Credit: Adapted from Fig.
What are the types of polymers?
The eight most common types of synthetic organic polymers, which are commonly found in households are:
- Low-density polyethylene (LDPE)
- High-density polyethylene (HDPE)
- Polypropylene (PP)
- Polyvinyl chloride (PVC)
- Polystyrene (PS)
- Nylon, nylon 6, nylon 6,6.
- Teflon (Polytetrafluoroethylene)
- Thermoplastic polyurethanes (TPU)
Is DNA a polymer?
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
What is an unbranched polymer?
Branched polymers are defined as having secondary polymer chains linked to a primary backbone, resulting in a variety of polymer architectures such as star, H-shaped, pom-pom, and comb-shaped polymers.
Is nylon a linear polymer?
Nylon is a linear polymer.
Is rubber a linear polymer?
Rubber is a natural polymer of Isoprene (2-Methyl -1, 3 – Butadiene). It is a linear, 1, 4 – addition polymer of Isoprene. Natural rubber has elastic properties and it undergoes long range reversible extension even if relatively small force is applied to it. Therefore, it is also known as Elastomer.
