WebbNIPAM (200 mg) and TMAOBn (n = 4, 5 and 6) (5, 10, 20, 40 or 60 mg) were dissolved in toluene (2 mL), and AIBN (20 mg) was added as initiator. The reaction mixture was flushed with nitrogen for 10 minutes and placed in an aluminium block dry bath at 70 °C under nitrogen atmosphere to initiate polymerization. WebbDATE. October 2024. Thermosensitive polymers are a class of “smart” materials that have the ability to respond to a change in temperature. Such polymers are uncommon as they are soluble in water at low temperature and become non-soluble when increasing the temperature. Because of their change of physical properties triggered by temperature ...
