Question

Based on their structure, all plastics are linear in nature.

• A. True
• B. False

Answer 1

The correct option is B False

Based on the connections between their monomer units, plastics are classified as linear and cross-linked plastics.

$\bullet$ Linear plastics: the monomer units are connected in linear fashion.

$\bullet$ Cross-linked plastics: cross-links exists between two linear or branched chains, forming a three-dimensional network.


This arrangement of monomer units define the properties of polymers. Linear polymers can be bent easily, whereas bending cross-linked polymers is difficult.
