• Simple but effective: Spontaneous synthesis of homogenous polymer networks

  07-09-2018 17:05
  Researchers have developed a spontaneous polymer network synthesis that allowed for the preparation of gels containing narrow molecular weight distribution polymers. The gel networks showed swelling properties that were responsive to temperature and solvent concentration. The reported process demonstrates the potential for facile preparation of high quality materials that exhibit the full range of polymer gel properties, including sustained release, stimuli responsiveness, and molecular sieving,
