Question

Among the following, the branched chain polymer is:
A.PVC
B.polyester
C.low density polyethylene
D.nylon-6,6

Answer 1

A polymer is a macromolecule or large molecule which is essentially a combination of many subunits. Polymers may be naturally found in plants and animals (natural polymer) or may be man-made (synthetic polymers).

Complete step by step answer:
We know that when linear chains of one polymer form some branches, then, such polymers are known as branched chain polymers. Low-density polyethylene has a branched chain structure. We can draw its structure in the following way.

So, the correct answer is Option C.

Additional Information:
Polymers are classified in the following way:
1)Linear polymers
2)Branched chain polymers
3) Cross-linked polymers.

In terms of the polymerization, polymers are classified as,

1. Addition polymerization
2. Condensation polymerization

In terms of the monomers, polymers are classified as,

1. Homomer
2. Heteropolymer

In terms of the molecular forces, polymers are classified as,

1. Elastomers
2. Fibres
3. Thermoplastics
4. Thermosetting polymers

In terms of the backbone chain, polymers are classified as,

1. Organic polymers
2. Inorganic polymers

Note:
There are two types of average molecular masses of Polymers. These are:
1)Number Average Molecular Masses
2) Weight Average Molecular Mass
Some important properties of polymers are:

1. As chain length and cross-linking increases the tensile strength of the polymer increases.
2. Polymers do not melt down, they change from crystalline state to semi-crystalline state.
3. Polymers with Van der Waals that links chains are weak, but they produce the polymer with a low melting point
