Three dimensional molecules with cross links are formed in the case of a
Options
(a) thermoplastic
(b) thermosetting plastic
(c) both
(d) none
Correct Answer:
thermosetting plastic
Explanation:
Thermosetting plastic 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 causes a reaction to occur between the chains, thus producing a complex cross-linked polymer.
