Co-Polymer sequence determination over the molar mass distribution by size-exclusion chromatography combined with pyrolysis - gas chromatography

Wouter C. Knol et al.

Summary: The chain sequence of copolymers plays a crucial role in determining their physical properties. However, there are limited analytical methods available for monitoring the sequence of copolymers. In this study, the authors investigated the use of pyrolysis - gas chromatography (Py-GC) as an alternative method and successfully combined it with nuclear-magnetic-resonance spectroscopy (NMR) to obtain quantitative information on the chain sequence and composition of random and block copolymers.

Expansion of the application range of pyrolysis-gas chromatography to copolymer sequence determination: Acrylate copolymers

Wouter C. Knol et al.

Summary: This study developed a pyrolysis-GC-MS method to determine the sequence distribution of complex copolymers. The method showed good applicability in binary acrylate copolymers and achieved some success in tertiary acrylate copolymers.
