In industrial chemistry, a stabilizer or stabiliser is a chemical that is used to prevent degradation. [1] Above all, heat and light stabilizers are added to plastic and rubber materials because they ensure safe processing and protect products against aging and weathering.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

4-Vinylbenzyl chloride is an organic compound with the formula ClCH 2 C 6 H 4 CH=CH 2. It is a bifunctional molecule, featuring both vinyl and a benzylic chloride functional groups . It is a colorless liquid that is typically stored with a stabilizer to suppress polymerization.
Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...
Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
Drilling stabilizer, part of the bottom hole assembly in oil drilling; Gyroscopic stabilizer (disambiguation), on ships and aircraft; Gun stabilizer, or gyrostabilizer, a device that helps a moving tank's gunner to aim the gun; Sway bar, a bar linking the two sides of an automotive suspension; Stabilization pond, a way of stabilizing wastewater
It is added as a stabilizer and polymerisation inhibitor to butadiene, styrene, [5] vinyl acetate, divinylbenzene [6] and other reactive monomer streams. [7] TBC is also used as a stabilizer in the manufacture of polyurethane foam. [8] It also can be used as an antioxidant for synthetic rubber, polymers and oil derivatives. [7]
Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. [1] Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. In short, the chemical reaction in which two or more ...
