摘要: Highly porous polyurethane foams were prepared by the particulate-leaching technique, using NaCI as water-soluble solid phase. Melt compounding and compression moulding used to prepare polymer/salt composite samples. Foams with controlled porosity, surface/volume ratio pore dimension distribution therefore obtained after dissolution of salt in distilled water. Dissolution kinetic was evaluated modelled a function filler composition its size distribution. Kinetic increased rising concentration reducing average size. Mechanical properties correlated their morphological structure polymeric component.
