[Analysis Case] Chemical Decomposition - Analysis of Polyurethane by GC/MS Method

Detailed structural analysis of condensation polymers is possible.

When conducting structural analysis of condensation-type polymers such as polyurethane, information may not be sufficiently obtained using only thermal decomposition GC/MS. In such cases, performing chemical decomposition using methanol can provide more detailed structural information. This case presents the results of decomposing polyurethane-based lightweight aggregate with methanol and conducting GC/MS measurements. Diphenylmethane diisocyanate, dimethyl phthalate, trimethylolpropane, and propylene glycol compounds were detected, leading to the conclusion that this product is composed of polyester urethane made from these materials.
