Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
Polyesters are condensation polymers
|
|
|
Alkenes and halogenoalkenes can form addition polymers
|
|
|
Addition polymers are always made up of two different types of monomer
|
|
|
None of the above
|
Detailed explanation-1: -Statement 1 saying “Thermosetting polymers are reusable” is incorrect as “thermosetting polymers can-not be recycled or used even after heating because they can sustain over a high value of temperature and permanently hardened once set to a shape". Hence, the correct answer is option 1.
Detailed explanation-2: -Terylene (or dacron) is not an example of addition polymer.
Detailed explanation-3: -A copolymer is a polymer formed when two (or more) different types of monomer are linked in the same polymer chain, as opposed to a homopolymer where only one monomer is used.
Detailed explanation-4: -Copolymers: The polymers made by addition polymerisation from two different monomers are known as copolymers, e.g., Buna-S.
