Three dimensional molecules with cross-links are formed in case of

Options

A. Thermoplastic
B. thermosetting plastic
C. Both (1) and (2)
D. None of these

Answer

B

Explanation

Thermosetting plastic have three dimensional cross linked strucutre . Such polymers are prepared in two steps . The first step in the formation of long chain molecules which are capable of futher reaction with each other . The second step is the application of heat which cause a reaction to occurs between the chains , thus producing a complex cross linked polymer .
