MCQ
Pick out the incorrect statement amongst the following.
  • Nylon clothing can stand high temperature and are therefore good to wear in summers.
  • B
    Thermosetting plastics do not become soft on heating.
  • C
    Addition polymers are formed without the elimination of by$-$product molecules.
  • D
    Natural rubber is obtained as latex from rubber trees.

Answer

Correct option: A.
Nylon clothing can stand high temperature and are therefore good to wear in summers.
Nylon is very much suitable for hosiery and the knitted fabrics because of its smoothness, light weight and high strength. Nylon is a lustrous fibre.
Thermoset materials are generally stronger than thermoplastic materials due to this three$-$dimensional network of bonds $($cross$-$linking$),$ and are also better suited to high-temperature applications up to the decomposition temperature.
Natural rubber is obtained as latex from rubber trees.
An addition polymer is a polymer which is formed by an addition reaction, where many monomers bond together via rearrangement of bonds without the loss of any atom or molecule.
