Definitions [3]
Define thermosetting polymers with two examples of them.
Thermosetting polymers are cross-linked or heavily branched polymers which get hardened during the molding process. These plastics cannot be softened again on heating. Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.
Define rubber.
Polymers which are elastic in nature are called rubber.
Answer the following in one sentence.
Define the term: Vulcanization
The process by which a network of cross-links is introduced into an elastomer is called vulcanization.
