ABSTRACT
The polycondensation of tetrahydrofuran with maleic anhydride catalyzed byMaghnite-H+ (Mag-H) was investigated. Maghnite is a montmorillonite sheet silicateclay that is exchanged with protons to produce Maghnite-H [1]. It was found that thepolymerization in bulk is initiated by Mag-H in the presence of acetic anhydride at 40°C.The effects of the amounts of Mag-H and acetic anhydride were studied. Thepolymerization yield increased as the proportions of catalyst and acetic anhydride wereincreased.
