Bakelite, the first commercially produced polymer, contains monomer units of phenol and formaldehyde. If an item made of Bakelite were broken, it could not be melted down and reformed. Is Bakelite a thermoplastic or thermosetting polymer? Can Bakelite be recycled?

Expert Solution & Answer

Interpretation Introduction

Interpretation: Bakelite, a thermoplastic or thermosetting plastic has to explained. Bakelite can be recycled or not has to be explained.

Concept Introduction:

Thermoplastics are polymers which gets melted on heating and can be reshaped. These are formed by addition polymerisation reaction and are linear in structure.
They are recyclable and reshaped.
Examples are Polystyrene, Polyethylene, PVC, Teflon, etc.
Thermosetting plastics are polymers which become hard and infusible solid on heating. These are formed by condensation polymerisation reaction and possess three dimensional cross linked structures.
They are not recyclable and reshaped.
Examples are Melamine formaldehyde resin, bakelite etc.

To Explain: whether bakelite is a thermoplastic or thermosetting plastic also explain whether bakelite can be recycled or not.

Answer to Problem 24.1QP

Answer

Bakelite is a thermosetting plastic
No, bakelite cannot be recycled.

Explanation of Solution

Bakelite is a polymer which is formed by the condenstion of monomer units of formaldehyde and phenol. It is also called as phenol formaldehyde resin. It a thermosetting plastic with three dimensional cross linked structure. It cannot be reshaped or recycled.

Bakelite is a thermosetting plastic and hence, it cannot be recycled.

Conclusion

Bakelite, a thermoplastic or thermosetting plastic and bakelite can be recycled or not were explained.
