The main goal of this Project is to study a influence of chemical structure of the polymer unit on the gas transport parameters by the methods of the conformational analysis, method Monte Carlo and molecular-dynamic method. The main objectives of the project are:

  • To develop and analyze new correlations between conformational rigidity parameters (CRP), small-scale mobility parameters (SSMP) and transport properties of glassy polymers as well as other physicochemical properties.
  • On the basis of the correlations, to formulate the desired design of glassy homo-polymers and copolymers that would provide improved permselective characteristics.
  • To prepare novel corresponding glassy polymers and study their gas permeation properties.
  • To find relations between CRP and small-scale mobility parameters (SSMP) of new polymers by the conformational probe method.
  • To investigate dynamic processes in the polymer-gas system by molecular simulation techniques and compare the simulation data with experimental and theoretical data.
  • To refine correlations between CRP, SSMP and the transport parameters of glassy polymers on the basis of obtained experimental and simulation data and improve the methods of search for advanced membrane materials using CRP and SSMP as input parameters.
  • To develop a novel unified approach for description of gas transport in glassy polymers, which would combine the free volume model and transition state theory since the parameters of both should be related to conformational mobility of glassy polymer chains.

The compulsory important part of the Project is the examination of the developed polymeric materials in gas tranport.

 

 

 

 

Cooperation

 

 

 

 

five research teams (two from INTAS members, three from Russia) with complementary expertise will be involved in the project. Theoretical and simulation methods will be used for study of gas transport of glassy polymers . Theoretical investigations will be supported by the experimental studies.
