On the thermal behaviour under dynamical conditions of succinic anhydride grafted polyolefins. A study from the crystalline regions

Variations related to the thermal behaviour of succinic anhydride modified polyolefins are discussed in this work. Changes in fusion/crystallization s teps recorded under dynamical conditions using differencial scanning calori metry are studied. The main goal of this work is to demonstrate the influen ce of reaction conditions on the behaviour of modified polymers, as well as the role played by the substituent grafted in the polyolefins under study. Differences in fusion and crystallization temperatures and in crystallinit y assumed, to be due to the grafted groups (and then to the reaction condit ions) are discussed.
