Abstract:

In-phase and quadrature dynamic FTIR spectra of polyurethane with 5Hz stretching under 100Hz phase modulation were presented. Four type carbonyl groups refer to molecular elastic and viscous changes in the polyurethane were clearly identified.

Key words: dynamic FTIR, polymer stretching, polyurethane
