Quick Answer: What Is A Branched Structure?

What is the difference between linear branched and crosslinked polymers?

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..

Why is cross linking important?

Cross-link is a bond which links one polymer chain to other. … Cross linking increases the molecular mass of a polymer. Cross-linked polymers are important because they are mechanically strong and resistant to heat, wear and attack by solvents.

What is the simplest polymer?

For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE).

What does it mean for a molecule to be branched?

Branched: A molecule or polymer with a nonlinear backbone. Branches sprout from one or more atoms of the main skeleton (or from monomers along the chain of a polymer).

Are proteins branched polymers?

To the best of my knowledge proteins are unbranched linear polymers, individual amino acids forming peptide bonds by liberation of water. … Other than these proteins also have covalent modifications i.e. disulphide linkages that can be intramolecular or intermolecular.

What is branched chain 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.

Which of the following is branched polymer?

Answer. ▶Low density polymer are branched polymer.

Which is not a polymer?

Ice is not a polymer. Whereas all the others are polymers of glucose and/or fructose.

What is the need for making polymers?

Polymers are very important, be it Polymers like Teflon, used in kitchen, or Nylon-6 type polymers used as a dress material. Monomers do not have the qualities of serving as a good purpose and only when they combine to form polymers, their purpose is realised. Hence, it is necessary to make polymers.

What is cross linking of polymers?

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.

What are linear and branched polymers?

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. Special types of branched polymers include dendrimers.

Is PVC a branched polymer?

Classification Based on Structure of Polymers: [1] Linear Polymers: These polymers consist of long and straight chains. The examples are high density polythen, PVC, etc. [2] Branched Polymers: These polymers contain linear chains having some branches, e.g., low density polythene.
