Discover Everything about Your Material: Comprehensive Study on PMMI

PMMI (Polymethacrylmethylimide) is a thermoplastic polymer. As it is an amorphous polymer, it features high transparency. The case study describes how thermal analysis methods can be employed to discover everything about the material.

PMMI (Polymethacrylmethylimide) is a thermoplastic polymer. As it is an amorphous polymer, it features high transparency. Therefore, it can be used in specific applications such as the automotive industry for headlight modules, or more generically for optical components like light guides, lenses, fiber optics, luminaire covers, sight glasses and cover lenses.  Methods of thermal analysis are widely used in the field of polymers to characterize and identify materials. In this case study, PMMI was investigated by means of DSC, TGA and TGA-FT-IR.  Key results include: 

Figure 1: DSC 214 Polyma results for the PMMA sample (blue curve) and for the PMMI sample (red curve)
Figure 2: Extracted IR spectrum for PMMI at 200°C (blue curve) compared to library spectrum for H2O (red curve)
