Q11P - Organic Chemistry (Mcmurry)

Question

Draw a segment of the polymer that might be prepared from 2-phenyl-1,3-butadiene.

Step-by-Step Solution

Answer

Polymerization

The process in which monomer comes together and forms the long-chain ( branched or linear long-chain) is known as polymerization.

The monomer used in polymerization are:

• Macromolecules “Huge-molecule”
• High molecular density molecule
• High molecular weight molecules

2-phenyl-1,3-butadiene preparing polymer

The monomer is used to form the polymer with the help of certain kinds of initiators (In). Upon decomposition, the unstable compound gives the radical or cation that will initiate the reaction further.

 

2-phenyl-1,3-butadiene monomer on polymerization form the polymer is the 1,2-addition process in which the monomer has four carbon chains with an alternative double bond. The polymer formed has a double bond where there was a single bond in the monomer and a single bond where there was a double bond in the monomer.

 

The polymer formed by monomer 2-phenyl-1,3-butadiene is shown as follows:
