| Sumario: | The deformation, temperature and time dependences of the STBMAMA copolymer have been studied; the relationship between creep and microhardness has been found. The results of ampicillin grafting onto the copolymer have been described; the effect on mechanical properties has been shown. Studies of the mechanical properties of solid polymers make it possible to reveal the polymer deformations and provide information on micromechanical mechanisms that determine the respond of the polymer to external thermal and power impacts in different physical states. In this paper, the results of a more detailed study of the structure and physicomechanical properties of polymers is aimed at obtaining information about the conformation dynamics of molecular chains, i.e., the dynamics and kinetics of motion of molecular nanosegments capable of moving as a whole relative to other sites. |
