Dec 19, 2019 · The ingredients i.e. Hexamethylenediamine and adipic acid are combined with water in a reactor. The outcome of this process is the nylon salt which is sent for evaporation which removes any excess water. The nylon salt is then passed through a reaction vessel where a continuous polymerization process makes molten Nylon 6,6.

Condensation Polymerization - Science Struck

Polymerization is a chemical process which involves the reaction of two or more monomers to form a polymer. There are two types of polymerization: Addition Polymerization; Condensation Polymerization; In addition polymerization, two or more molecules of monomers attach together to form a polymer. It is a chain reaction and no byproduct is release.

What Is Runaway Polymerization? | Sciencing

A runaway polymerization is a potentially dangerous reaction in which chemical products form with excessive speed, producing heat that may lead to an explosion or other hazards. Because polymerization is an essential process for making many synthetic materials, chemists adopt strategies to maintain safe reactions and avoid runaway polymerization.

Chain-Reaction Polymerization. Chain-reaction polymerization, sometimes called addition polymerization, requires an initiator to start the growth of the reaction. The largest family of polymers 3, vinyl polymers, are produced by chain polymerization reactions.A good example is the free-radical polymerization of styrene, which is initiated by a free radical (R) that reacts with styrene.
