(a)
Interpretation:
The given term plasticizer has to be determined.
Concept Introduction:
Polymers are macromolecules which are formed a by number of repeating units called monomers.
(b)
Interpretation:
The reason for why DEHP is added to PVC during manufacture has to be indicated.
Concept Introduction:
Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.
Polymers are macromolecules which are formed a by number of repeating units called monomers.
(c)
Interpretation:
The two reasons for banning DEHP have to be explained.
