Classification Of Polymerization Inhibitor

There are many types of polymerization inhibitors. First, they can be divided into two categories: Free-based and non-free-based or molecular-based polymerization inhibitors. Non-free-based polymerization inhibitors can be divided into phenolic polymerization inhibitors, ether polymerization inhibitors, quinone polymerization inhibitors, aromatic amine polymerization inhibitors and so on according to different substituents. The main varieties of polymerization inhibitors are introduced below by chemical structure classification.

 

Phenolic polymerization inhibitors: Hydroquinone, p-hydroxyanisole, 2, 6-di-tert-butyl p-cresol, 2, 5-di-tert-butyl hydroquinone, 2-tert-butyl hydroquinone.

 

Quinone inhibitors: P-benzoquinone, methyl hydroquinone (THQ).

 

Inorganic compound polymerization inhibitor: Commonly used are ferric chloride, cuprous chloride, copper sulfate, titanium trichloride, sodium sulfate, ammonium thiocyanate.

FAQ

 

 

Q: What is a polymerization inhibitor?

A: Polymerization inhibitors are reagents which are used to prevent undesirable polymerization by light or heat. Conventional polymerization inhibitors, such as hydroquinone, are at a disadvantage because they cannot prevent polymerization under certain conditions.

Q: What is polymerization and why is it important?

A: Polymerization is the process to create polymers. These polymers are then processed to make various kinds of plastic products. During polymerization, smaller molecules, called monomers or building blocks, are chemically combined to create larger molecules or a macromolecule.

Q: What are the common polymerization inhibitors?

A: The polymerization inhibitors commonly applied in the industry are phenolic, amines and free radical-nitroxide compounds.

Q: What is the polymerization inhibitor for styrene?

A: Quinone methide derivatives such as 4-benzylidene-2,6-di-tert-butyl-cyclohexa-2,5 dienone are used to inhibit styrene monomer polymerization in the dehydrogenator portion of a styrene monomer production system.

Q: How do polymerization inhibitors work?

A: Polymerization inhibitors work by scavenging and neutralizing free radicals that initiate and propagate polymerization reactions. Free radicals are highly reactive molecules that can trigger chain reactions and lead to the uncontrolled growth of polymers.
