CHE SIGNIFICA POLYISOPRENE IN INGLESE
Gomma sintetica
La gomma sintetica, invariabilmente un polimero, è qualsiasi tipo di elastomero artificiale sintetizzato principalmente da sottoprodotti di petrolio. Un elastomero è un materiale con la proprietà meccanica che può subire una deformazione molto più elastica sotto stress rispetto alla maggior parte dei materiali e restituisce ancora alla sua dimensione precedente senza deformazioni permanenti. Si producono annualmente circa 15 miliardi di gocce di gomme, di cui due terzi sono sintetiche. I ricavi globali generati con gomme sintetiche potrebbero salire a circa 56 miliardi di dollari nel 2020. La gomma sintetica, come la gomma naturale, utilizza nell'industria automobilistica pneumatici, profili per porte e finestre, tubi flessibili, cinture, tappetini, pavimenti e smorzatori.

High-cis Polyisoprenes NR is almost 100% cw-polyisoprene. Polyisoprene with
very high cw content (97%) (Van, 1966) can be produced by titanium-based
Ziegler-Natta polymerization, but anionic polymerization can also produce
polymers ...

This "associative" structure is gradually destroyed, and partly when the
polyisoprene is dissolved in a conventional solvent. However, in very many
cases, a proportion of the NR remains insoluble in such solvents; this fraction is
commonly ...
For the particular artificial synthetic cis-1,4-polyisoprene latex investigated by
Preiss. Sawyer and Simpson [26] (see further below), the mass median particle
diameter was ca. 0.9 um; this is similar to that of many natural rubber latices.
