The pyrolysis-GC revealed that the mer unit MMA was the main component in all analyzed polymer powders. MMA was easily observed because polymers based on MMA degrade to the original monomer, ie, depolymerization.
The THF-soluble polymer of the one-paste system T was identified by IR as a polymethacrylate,and the main component in the methanol soluble part was the monomer UEDMA according to HPLC analysis.
