dc.description.abstractThe oxidative thermal degradation of poly(2-chloroethyl methacrylate) (PCEMA) was studied in the presence of the following commercial antioxidants: CHIMASSORB 119 (CH 119) and CHIMASSORB 944 (CH 944), both based on amines, and a mixture of IRGANOX 1010, a phenol derivative, and IRGAPHOS 168, a phosphite (mass ratio 1:1), by the thermogravimetric (TG) method. On the basis of the obtained results, the characteristic temperatures of 10% mass loss, Tio%, the shape of the differential TG (DTG) curves and mean values of the thermal degradation activation energy, Ea, it was concluded that the commercial photostabilisers CH 119 and CH 944 could not successfully stabilize the thermal degradation of PCEMA, while in the case of the presence of the antioxidant mixture IRGANOX 1010 and IRGAPHOS 168 (1:1) slight stabilizing effects were observed.en
dc.description.abstractU radu je ispitana oksidativna termijska degradacija poli(2-hloretil metakrilata) (PCEMA) u prisustvu komercijalnih antioksidanata amino tipa CHIMASSORB 119 (CH 119) i CHIMASSORB 944 (CH 944) i smeše antioksidanata, IRGANOX 1010, fenolnog derivata, i IRGAPHOS 168, fosfita (maseni udeli 1:1). Ispitivanja su izvedena termogravimetrijskom (TG) metodom, a na osnovu karakterističnih temperatura 10% gubitka mase, oblika diferencijalnih TG (DTG) krivih i srednjih vrednosti energije aktivacije termijske degradacije, ispitivan je uticaj pojedinih antioksidanata.sr
