 Abstract
The kinetic parameters (activation energy, reaction order, reaction enthalpy and preexponential factor) of a copolymer INFINEUM SV 260 were determined using the multilinear regression analysis of a TGA curve.
The same procedure is also applied to some experimental TGA curves obtained for the exothermal decomposition of INFINEUM SV 260.

 Rezumat
In cadrul acestui articol sunt prezentate cele mai importante aspecte ale comportării termice ale copolimerului INFINEUM SV 260. Cu ajutorul regresiei multiliniare am determinat parametrii cinetici corespunzători descompunerii termice a copolimerului: energia de activare, factorul preexponenţial, ordinul de reacţie şi coeficieţii de corelaţie.
