چکیده
|
Maghnite is a montmorillonite sheet silicate clay that is exchanged with protons to produce maghnite-h+ (mag-h+). this non-toxic and cheaper cationic catalyst was used for the copolymerization of ε-caprolactone (cl) with tetrahydrofuran (thf),in presence of acetic anhydride (aa). the effects of the amounts of mag-h+,acetic anhydride and the temperature on the synthesis of poly (ε-caprolactone-co-tetrahydrofuran) were studied. the copolymer obtained was characterized by 1h-nmr and ir spectroscopy.
