Plastics — Polyols for use in the production of polyurethanes — Determination of degree of unsaturation by using iodine method

General information

Current stage: 60.00 Effective date: 28 gush 2024

Originator: ISO

Owner: ISO/TC 61/SC 12

Type: International Standard

Scope

This international standard specifies a method for quantifying the total unsaturation using an addition reaction of the interhalogen compound ICl (iodine monochloride) using glacial acetic acid as a solvent as a method for measuring the total unsaturation of a polyether polyol for polyurethanes. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group
