Background Nylon is a polyamide that is formed from the condensation reaction of adipic acid (a dicarboxylic acid) and 1,6 – diaminohexane (a diamine). A scientist working for DuPont, Wallace Carothers discovered Nylon in 1935 and its name is a contraction of New York and London. When Nylon was first discovered it was
In polymer chemistry, branching occurs by the replacement of a substituent, e.g., a hydrogen atom, on a monomer subunit, by another covalently bonded chain of that polymer; or, in the case of a graft copolymer, by a chain of another type.Branched polymers have more compact and symmetrical molecular conformations, and exhibit …
An introduction to polyamides – including nylon and Kevlar
For something most of us interact with on a daily basis, nylon remains fairly elusive. So just how sustainable is nylon?
Polymerisation – Addition Polymerisation (1) Mechanism : Simply put, addition polymerisation is the reaction where alkenes (unsaturated molecules) are reacted to produce long chain molecules (macromolecules or polymers).
History. Aromatic polyamides were first introduced in commercial applications in the early 1960s, with a meta-aramid fiber produced by DuPont as HT-1 and then under the trade name Nomex. This fiber, which handles similarly to normal textile apparel fibers, is characterized by its excellent resistance to heat, as it neither melts nor ignites in …
