Record 2 2011-01-06

English

Subject field(s)
  • Chemical Elements and Compounds
  • Rubber
Universal entry(ies)
CONT

Polyisoprene is produced by solution polymerization using Ziegler-Natta catalysts. The cis-1,4-polyisoprene is a synthetic equivalent of natural rubber. However, the synthetic polyisoprenes have cis contents of only about 92 to 96%; consequently, these rubber differ from natural rubber in several ways.

OBS

The prefixes "cis-" and "trans-" must be italicized.

OBS

Also known under the following trade names: Betaprene H; Isoprene D.

OBS

Chemical formula: (C5H8)x

OBS

In the chemical formula, the "x" in subscript (or the "n" in subscript in French) replaces a number and is written in italic.

Nom générique de polymères de l'isoprène ayant pour formule brute (C5H8)n.

OBS

Dans la formule chimique le «x» en indice (en anglais) ou le «n» en indice (en français), qui joue un rôle de caractère de substitution pour un nombre quelconque, s'écrit en italique.

OBS

Les préfixes «cis-» et «trans-» s'écrivent en italique.
