Options:
A) Thermoplastic
B) Thermosetting plastic
C) Both
D) None
Show Answer
Answer:
Correct Answer: B
Solution:
Thermosetting plastics have three dimensional cross-linked structure. Such polymers are prepared in two steps. The first step is the formation of long chain molecules which are capable of further reaction with each other. The second step is the application of heat which cause a reaction to occur between the chains, thus producing a complex cross-linked polymer.
