Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are polymers made?
A
by closing double bonds
B
by opening up double bonds
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -To form a polymer of molecules, the double carbon to carbon bonds are broken to become single bonds . Another important aspect is the open bonds at both ends of the polymer to allow for more linking of molecules. To change from a double bond to a single bond, replace the C = C to C – C.

Detailed explanation-2: -Assorted combinations of heat, pressure and catalysis alter the chemical bonds that hold monomers together, causing them to bond with one another. Most often, they do so in a linear fashion, creating chains of monomers called polymers.

Detailed explanation-3: -An important property of the polymers containing carbon–carbon double bonds in the backbone is their capability to be vulcanized. Vulcanization is the process of introduction of some crosslinking bridges between the polymer molecules.

Detailed explanation-4: -Polymers are formed by two main ways called addition and condensation polymerization. In addition, polymerization, an initiator (or catalyst) reacts with a starting monomer.

Detailed explanation-5: -Monomers join together to make polymer chains by forming covalent bonds-that is, by sharing electrons. Other bonds then hold the groups of chains together to form a polymer material.
