This document describes the application of GPC triple detection analysis of polybutadiene using the Agilent 390-MDS Multi Detector Suite. Polybutadiene is an elastomer with high elasticity and recovery. It is commonly used to coat electronic assemblies and for tire production. The document provides detailed information on experimental conditions and instrument setup.
This document details the analysis of polybutadiene, a synthetic rubber, using Gel Permeation Chromatography (GPC) with triple detection. The method combines a light scattering detector, a viscometer, and a differential refractive index detector to determine accurate molecular weights for polymers where narrow standards are unavailable.
The note outlines the specific experimental conditions, including the use of Agilent PLgel MIXED-C columns, THF eluent, and a flow rate of 1.0 mL/min. Results demonstrate that the 390-MDS system can effectively characterize polybutadiene samples, revealing structural similarities and differences in molecular weight distributions resulting from synthesis methods.
