Why is polymerization hazardous?
Vigorous polymerization is potentially hazardous because the reaction may get out of control. Once started, the reaction is accelerated by the heat that it produces. The uncontrolled buildup of heat and pressure can cause a fire or an explosion, or can rupture closed containers.
What is polymerization hazard?
A hazardous polymerization is a chemical reaction that produces a very high and dangerous amount of heat due to how rapidly the reaction takes place. Polymerization is a chemical reaction where one or more small molecules combine together to form a larger molecule.
What are the conditions of polymerization?
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
What is polymerization give an example of polymerization reaction?
Polymerization reactions are chain reactions, and the formation of Teflon from tetrafluoroethylene is one example. In this reaction, a peroxide (a compound in which two oxygen atoms are joined together by a single covalent bond) may be used as the initiator.
Which is the most common hazardous chemical?

What is the main difference between the two types of polymerization?
Difference Between Addition And Condensation Polymerization
| Addition Polymerization | Condensation Polymerization |
|---|---|
| Produces no by-products | By-products such as ammonia, water and HCl are produced |
| Addition of monomers results in polymers | Condensation of monomers result in polymers |
What are three natural polymers?
Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins. In our previous section on network polymers, we mentioned vulcanized rubber and pectin.
What are two methods of polymerization?
There are two general types of polymerization reactions: addition polymerization and condensation polymerization.
