Keywords:

  • unusual property of water - increasing glass transition temperature;
  • plasticizers - softening effect in polymers;
  • rigidifying effect of small amounts of plasticizer - antiplasticization;
  • indomethacin - molecule serving as comparative reference;
  • preselected conditions of partial pressure of water vapor - humidity controls of the instrument;
  • sorption of small amounts of water by a substrate - result in substrate-water interactions;
  • water - ability to restrict molecular mobility of polymer
