Neoprene AKA waders and Polychloroprene-D-MSHFDS


The technical name of Neoprene is Polychloroprene. It's Monomer structural formula is C⁴H⁵Cl.
Neoprene is a synthetic polymer. We know that Neoprene is not biodegradable because it is very environmentally unfriendly.


Physical Properties -
Many physical properties of neoprene include the density which is (g/cm3) = 1.23000E+00. It's texture is mostly smooth and rubber-like. It's melting point is around 40 degrees Celsius. It has many properties similar to rubber being that it is resistant to sun and weather damage; also that it resists well to twisting or flexing.

Chemical properties -
The chemical properties of neoprene are that it resists well to many reactions with other compounds or solutions. It is water proof so it does not react with water or oils at all.

Linking Monomers -
Neoprene's Monomers are linked by addition to form the Polychloroprene Polymer. To add the Monomers together, the hydrogens on each end of the molecule break off and bond with the corresponding hydrogen breaking off from the connecting molecule to form hydrogen gas (H2). The two Carbons on either side of the Monomer then form single bonds with the Carbons on the other Monomer, joining the two in a chain.

Cross Linkage -
Cross linkage does occur and the significance is that it cross links with sulfur through vulcanization. Vulcanization is where atomic bridges of sulfur are formed between the chain of chloroprene. This improves it and makes it tougher and more resitiant to heat and cold.

Practical Uses -
The Practical uses of neoprene are: Tires, wetsuits, sleeves for electronic devices, waders, gloves, and the liner for fire doors because it is synthetic.
