Effect of Heterometallic Biscitratogermanates (-stannates) of Co(II) and Ni(II) on the Polycondensation and Properties of PoIy(Glycol Maleate Phthalate) Copolymers

摘要

The ability of heterometallic Ge(IV) and Sn(IV) complexes Co(H2O)6Ge(HCitr)2 (I), Co(H2O)6 Sn(HCitr)2 (II), Ni(H2O)6Ge(HCitr)2 (III), Ni(H2O)6Sn(HCitr)2 (IV), Mg(H2O)6Ge(HCitr)2 (V), and Mg(H2O)6f Sn(HCitr)2 (VI) (H4Citr is citric acid) to activate polycondensation of maleic and phthalic anhydrides with ethylene glycol was studied. Copolymerization of modified poly(glycol maleate phthalate) with triethylene glycol dimethacrylate was performed, and the copolymer characteristics were determined.
