Influence of complexes of germanium(IV) and 3d-metals is traced with citric acid and 1,10-phenanthroline on the process of polycondensation maleic and phtalic anhydrydes with an ethyleneglycol. It is set that there is a noticeable decline of acidvalue of the got olygomer at the use of modifiers that testifies to the greater depth of polycondensation. Kinetic of copolymeryzation of the modified olygomers is studied with dithreeethylenglyc oldimethacrylatphtalates, threeethyenglycoldimethylmetacrylates and monoethyleneglycolm ethylacrylates, descriptions of the got interdimerss are certain. Is it rotined that substantial advantage of the studied modifiers is that they can be used for a temperature 30ºC, when copolymeryzation does not pass with unmodified polyglycolmaleinatphalates. Complex [Co(phen)3 ][Ge(HCit)2 ]·2H2 O substantially accelerates copolymerisation with three ethyenglycoldimethylmetacrylates; phenanthroline – with a monoethyleneglycolmethylacryl ates. At 60 ºC all studied complexes accelerate the reaction of copolymeryzation well enough. Determination of density, hardness and impact strength showed that the modification PGMP virtually no effect on the physico-mechanical characteristics of the obtained copolymers (for modified systems rates were only 5-10% higher). Thus, the density for modified systems made up of 1.16-1.18 g/cm3 (unmodified system 1,13 g/cm3 ) hardness 17-18 N∙m (unmodified to 16 N∙m), and impact strength of 13 kJ/m2 (unmodified – 12 kJ/m2 ). Thus, the copolymerization m-PGMF with EBA was studied, takes place not only with greater speed but also at a temperature of 30°C without the use of special additive activated components. This may be particularly important in the case of manufacture of large dimensions products and the construction of roads, dams, bridges. Industrial application of the studied modifiers does not require significant changes to existing technologies and can be implemented by the addition of dry or activator solution into the reaction mixture before the polycondensation.
