Thermoplasts
- A.have a three-dimensional network of primary bonds as polymerization proceeds in all directions
- B.are long chain molecules held together by secondary bonds
- C.have decreasing ability to deform plastically with increasing temperature
- D.have secondary bonds and as the thermal energy increases, the secondary bonds never break
Show answer
In a thermoplastic the polymer exists as long linear or lightly branched chains, and one chain is held to the next only by weak secondary forces such as van der Waals attraction.
