Types Of Polymerisation Reactions

Bakelite is a thermosetting polymer and one of the first synthetic plastics. It is synthesized through a condensation reaction between the following monomers:

Phenol ( ), and Formaldehyde ( ). The reaction involves the formation of a phenol-formaldehyde network, resulting in a hard, durable polymer known as Bakelite.

Key Points: Bakelite is widely used in electrical insulators and household items due to its high mechanical strength and heat resistance. Phenol and formaldehyde undergo a condensation reaction to form a polymer with cross-linked structures. Thus, the monomers of Bakelite are

Phenol and Formaldehyde.

A cyclotron accelerates charged particles using a perpendicular magnetic field and an alternating electric field.

The principle involves the Lorentz force: where: is the charge of the particle, is the velocity, is the magnetic field.

The magnetic field forces the charged particles into a circular trajectory, while the electric field accelerates them each time they cross the gap between the dees.
