This work aims to study the behavior of temperature-responsive p(NIPAM) and temperature/pH-responsive p(NIPAM)/acrylic acid (AA) microgels. Three microgels were synthesized using surfactant free emulsion polymerization technique, these are p(NIPAM), p(NIPAM)-co-AA 95:5% (w/w) and p(NIPAM)-co-AA 90:10% (w/w). Dynamic light scattering was used to study the behavior of diluted microgel dispersions (0...
The results have recently been reported of a preliminary study into the base catalysed hydrolysis of methyl paraben as a test and reference reaction for flow-through microcalorimeters. The values quoted for the rate constant and the molar enthalpy change are (3.15+/-0.11)x10 -4 s -1 and -50.5+/-4.3kJmol -1 , respectively. The present paper explains the results...
