Skladanyuk R. Kinetics of the process of filled epoxide polymers formations.

The complex of investigation of the kinetic regularity of process of formation of cross-linked epoxy-amine polymer in the presence of high dispersion fillers - aerosils with different nature of surface has been studied by the methods of differential thermal analise, IR-spectroscopy and rotational viscosimetry. It was done interrelation between kinetic consumption of the functional groups and level of sytem structurization. It was shown, that insertion of filler leads by effect of acceleration of process of the consumption of epoxide groups at initial polimerization stages undependence from nature of surface. The influence of nature surface of aerosil at reaction of epoxide-amine displays at deep stages that in the case of A-175 leads at significant of deceleration of a reaction and loss of boundary degree conversion of epoxyde and amine groups. It was shown, that it is possible to separate a few aspect of effect filler, which is connected with filler on the mechanism, velosity and boundary depth consum ption of functional groups; structural and kinetic aspect with is conditioned by filler effect on the correlation of velosities of the processes chemical and physical structurization, defining of structural organization of the cross-linked polymer and properties of the polymer matrix. It was obtained kinetic model of reaction epoxide-amine in the filled systems, whigh is consider singularities of the formation of the cross-linked structure of polymer matrix and physical structurization effects. It was calculated of basic kinetic parametres of process of the formation of filler epoxy-polymer matrixs with dependence from content and nature surface of filler. The lasts make used for optimisation of the temperature and time and conversial parametres of the process whith idea its intensification.
