Abstract

Hattab Youcef* and Benharrats Nacera

The copolymers are mixed materials synthesized from two polymers blended in optimized percentages. The objective of this study is to use the maghnite H + as ecocatalyser in the presence of monomers to obtain a copolymer polytetrahydrofuran- styrene by polymerization. The obtained results RX, RMN, IR and DSC confirmed the copolymerization of monomers and their stability. The studies done, such as the effect of the amount of catalyser and the amount of acetic anhydride on the syntheses of polytetrahydrofuran and polystyrene have proved the effectiveness of the Maghnite.
