dc.description.abstractA series of novel hydrophilic organic-inorganic composites (OIC) with enhanced sorption properties were synthesized by onepotsynthesistechnique-insituradicalpolymerizationofacrylamide(AM)andhydrolyticpolycondensationofsodiumsilicatein aqueous solution. Formation of mixed organic-inorganic polyacrylamide (PAM)/SiO2 phase has been detected by FTIR spectroscopy (appropriate changes in H-bonds network structure of PAM) and DSC analysis (dramatic decreasing glass temperature ofPAM).AdditivedecreasingofmasslossofOICwithincreasingofSiO2 contentisexplainedbytheincreasingofPAM-content in mixed PAM/SiO2 phase on the interface of organic and inorganic phases. The formation of SiO2 aggregates with different dispersity,which,intheirturn,formsubmicronstructuresincompositeswithSiO2 contentmorethan15wt.%wasobservedfrom SEMdata.StructurizationofOICresultedintheenhancedsorptioncharacteristics(swellingcapacityoftheOICreaches2730%).
