Difference Between Linear and Branched Polymers

Industry expert Tony O'Lenick explains the difference between a linear, branched and dendrimer polymer structure. The simplest polymer architecture is a linear chain: a single backbone with no branches. A branched polymer molecule is composed of a main chain with one or more substituent side chains or branches.

What is branching in polymers?

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.

What are linear and branched polymers can thermoplastics be branched?

Linear polymers are straight chains of polymers made up by carbon-carbon bonds. When branching occurs in this straight chain, branched polymers are formed. Thermoplastics can be branched polymers which can be remolded by temperature change.

What is linear chain polymer?

A linear polymer is simply a chain in which all of the carbon-carbon bonds exist in a single straight line. An example of a linear polymer is Teflon, which is made from tetrafluoroethylene. It is a single strand of units made from two carbon atoms and four fluorine atoms.

What is linear polymer in chemistry?

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 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)

What causes branching in polymers?

Branching is caused during polymerization at high pressure by growth sometimes starting from an initiation point in a chain rather than at the end. An alternative way of making polyethylene is at low pressure using a special catalyst, and this usually results in a highly linear chain without branching (HDPE).

Is amylopectin a linear polymer?

1.2 Starch

Starch is the major source of energy stored as a carbohydrate in plants. It is composed of two substances: amylose, which is a linear polysaccharide, and amylopectin, which is a branched polysaccharide. Both the forms of starch are polymers of α-D-glucose.

Is rubber a linear polymer?

Natural rubber is cis-1,4-Polyisoprene. It is linear polymer of isoprene.

Is Bakelite a linear polymer?

Nylon is a linear polymer.

Bakelite, polyester, polyvinyl acetate, SBR, polypropylene, nylon 6,6, thiokol, urea-formaldehyde resin, melamine formaldehyde resisn.

Is glycogen a linear polymer?

It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units. ... It is a linear polymer with the glucose units linked through β-1,4-glycosidic bonds.

Is isoprene a linear polymer?

Natural rubber is a linear polymer of isoprene (2-methyl-1, 3-butadiene) and is also called as cis-1, 4-polyisoprene.

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.
