General information

Current stage: 00.60 Effective date: Jul 28, 2022

Originator: ISO

Owner: ISO/TC 45/SC 3

Type: International Standard

Scope

This document specifies a method for the quantitative determination of the microstructure of polyisoprene 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 isoprene rubber.
