Abstract
The thermal degradation of the first six members of poly(mono-n-alkyl itaconates) by thermogravimetry (TG), differential scanning calorimetr y (DSC), Fourier Transform infrared (FTIR) and FTIR evolved gas analys is (FTIR-EGA) was studied. The degradation mechanism involves cyclic a nhydride formation followed by crosslinking due to the linear anhydrid e formation. In both processes water and/or alcohol evolution was dete cted. Also, decarboxylation processes take place on all polymers at hi gh temperatures (>180 degrees C). A mechanism of the degradation proce ss is proposed.
