INTRODUCTION:
Neoprene
is also known as polychloroprene. It is one kind of synthetic rubber. polymerization
is the process of small molecules (monomers) are combined chemically to produce
the chain like large molecules (polymer). The polymerization of chloroprene is
called as the neoprene. Neoprene is the colorless, toxic and flammable liquid.

Types:
Liquid neoprene
- Copolymers of neoprene
Properties
- Pressure sensitive, Heat or solvent activated adhesives
Uses:
- It is used for surface coatings, industrial and decorative coatings
Black neoprene:
- Black neoprene act as a good weather resistant
- It has mild resistance and have strong physical properties in petroleum based fluids.
White neoprene:
White neoprene
is mainly used in a food and beverage industries because of its lack of adhesives
and high security.
Preparation of neoprene:
Neoprene is prepared by using free radical polymerization method. In this method, vinyl acetylene is reacted with cuprous oxide in the presence of hydrochloric acid. It gives the chloroprene. This chloroprene is undergoes free radical polymerizations we will get the neoprene rubber.
Applications:
- Neoprene rubber is used as a insulator in power transformers, light bulbs, cables and shield for laptops.
- It is used as a safety equipment for making neoprene masks, gloves and clothes.
- Neoprene is used in the manufacture of wetsuits and diving suits because of it great water and thermal resistance.
- It is used for packaging.
