Determination of the microstructure of isoprene rubber (IR) — 1H-NMR method

General information

Current stage: 10.98 New project rejected Sep 13, 2023

Originator: ISO

Owner: ISO/TC 45/SC 3 Raw materials (including latex) for use in the rubber industry

Type: International Standard

Scope

This document specifies a method for the quantitative determination of the microstructure of synthetic isoprene rubber (IR) using 1H-NMR spectrometry. The relative content of three components in IR, cis1,4-, trans1,4-, and 3,4-polyisoprene can be calculated respectively.
This method is applicable for raw synthetic isoprene rubber.
