Studies of the viscoelastic properties of selected polymer systems by the dynamic mechanical analysis

Polimery 2002, No 9, 637


DOI: dx.doi.org/10.14314/polimery.2002.637

Summary

The review is presented of authors' research concerning application of DMA method for characterization of four, varied in properties, polymeric systems: (a) poly(vinyl chloride) modified with liquid crystalline products being oligomeric arylesters multisubstituted with chlorine (the effect of chemical structure of modifier on the glass temperature values of modified PVC samples); (b) new dental materials based on monometacrylates of glicols from ethyl to tetraethyl senes and three various non-aromatic diisocyanates (determination of crosslinking degree and molecular weights of chain fragments between network points of polymeric methacrylate-urethane systems crosslinked during radical polymerization); (c) polysiloxane compositions used as vibration damping materials (investigation of changes of storage modulus and loss tangent as functions of strain frequency and temperature); (d) natural bone transplants (investigations as in (c) of frozen and lyophilized bone samples).


Keywords: dynamic mechanical analysis, polymeric systems, viscoelasticity, damping
