For example, the catalysis used to polymerize ethylene molecules is called the Ziegler Natta catalyst, while a common catalyst for making synthetic rubber is organic peroxides. Natural Polymers There are four main categories of biological polymers that are so important to living things they have been...
Often an initiator such as benzoyl peroxide is added to the monomer to do the process ofpolymerization. In photo-polymerization, this initiator is being activated by the light. Further, it forms the material like a free radical or an ion radical. Then, it starts a chain reaction of polymeriz...

Understanding the direction of reactions is crucial inorganic synthesis. For Zaitsev eliminations, a small strongbaseis preferred, while bulkybasesfavor Hofmann eliminations. Markovnikov additions utilize HX oroxymercuration, whereasanti-Markovnikovreactions require HBr with peroxides. Starting with an alcohol...

It has other advantages being noncorrosive and chemically stable, forms no peroxides during storage, and hence presents no danger of degrading labile lipids.

weight thiols and selenols as well as sulfides and selenides have highly unpleasant and obnoxious odours, although the perception of theodouras unpleasant or pleasant can sometimes vary with the concentration of the particularcompound. Disulfides and diselenides are far more stable than peroxides, ...
