Quantitative Analysis of Copolymers using a Pyroprobe

Quantitative analysis of poly(styrene-isoprene) copolymers including RSDs and a calibration curve using a CDS Model 6150 Pyroprobe.

Analytical pyrolysis is a powerful tool for the qualitative analysis of polymers. The analysis usually starts from a simple pyrogram match to an existing pyrolysis database to identify the polymer chemical structure. If multiple polymers are identified, a quantitative method is often adopted by comparing peak areas of the pyrolysis products to determine each polymer ratio. In this application, styrene-isoprene block copolymers, which are large-volume, lowcost, commercial thermoplastic elastomers, are analyzed by following this approach.
