الملخص EN

A novel Copolymer was prepared by mixing polycarbonate and polyethylene with different ratios with maleic anhydride in molten state by using dicumyl peroxide as an initiator in nitrogen.

Thermodynamic melting constants of the Copolymer were determined by using Differential Scanning Calorimetry (DSC), it was found that the melting points Tm, and glass transition temperatures Tg were convergent in values with difference in the ratios of polycarbonate in the copolymer.

Enthalpy change value increases with the increase of polycarbonate ratio.

Kinetic study of degradation was carried out by using Thermo gravimetric Analysis (TGA), and it was found to be of overall second order, and thermodynamic constants of degradation were equivalent in their values.

Crystalline structure of the copolymer was studied
