Liquid chromatography/mass spectrometry identification of intermediates and vulcanization products by using squalene as vulcanization model compound

摘要

RATIONALE: Sulfur-vulcanized rubber is a three-dimensional polymer network, insoluble in all organic solvents. For this reason, vulcanization products are difficult to study and identify by conventional analytical techniques. To simplify this task, low molecular weight olefins have been used as model compounds (MCs) in place of rubber in vulcanization experiments.
