Current projects

Polyolefins characterization

Developpement of new methods for measuring the microstructure of polyolefins : molar mass distribution (MMD) and chemical composition distribution (CCD)

- determination of long chain branching (LGB) using viscosimeter detector

- determination of short chain branching (SCB) using CRYSTAF, TREF, CEF, TGIC, DSC and DSC-SIST

TGA coupling

The combination of TGA with a FTIR or GC-MS allows the online investigation of gaseous products formed during the degradation of the sample

Chemical composition of copolymer using infrared (NIR or MIR) and chemometrics

Fourier transform infrared spectroscopy by attenuated total reflection (ATR‐FTIR), combined with the partial least square (PLS) method provides a fast characterization of copolymers' intricate composition
