Abstract
The influence of the chemical structure both of polymer and plasticizer on the elasticity modulus has been analyzed. Consideration was made of the situation when the plasticized polymer is in the glassy or rubbery state. Description of the glassy state is produced basing on equation [1-2] containing the elasticity coefficient of atom bonds, the characteristic size of the bonds, and Van-der-Waals volumes both of the repeating units of polymers and molecule of plasticizer. Analysis for the rubbery state is based on the classic rubber elasticity theory. As a result the universal relationships are provided for description of the influence of chemical structure both of polymer and plasticizer on the modulus of elasticity.
