Three dimensional molecules with cross links are formed in the case of a
A
Thermoplastic
B
Thermosetting plastic
C
Both
D
None
Answer
Thermosetting plastic
Explanation
Solution
Thermosetting plastics have three dimensional cross-linked structures. Such polymers are prepared in two steps. The first step is the foramtion of long chain molecules which are capable of further reaction with each other. The second step is the application of heat which causes a reaction to occur between the chains, thus producing a complex cross-linked polymer.
