Calorimetric Analysis of Water Clusters in Polyethylene

摘要: The diffusion coefficient, D, of water in several polymers has previously been reported to decrease as the concentration is increased.1,2 From these findings, it inferred that mobility sorbed due clustering associated molecules polymer matrix.1,3 Probably this effect, D for polyethylene at 25°C found range from 1.5×10−7 1.1×10−6 cm2/sec.4,5 In addition, solubility, S, dependent upon structure and difficult measure since parts per million (ppm) range. Therefore, we have undertaken an experimental program determine saturation content isolate clustered vapor form.
