ABSTRACT:
Semi-permeable microporous polymer bodies, such as porous plates or membranes for separation processes, are provided, these being made of durable high-temperature thermoplastics, eg., a liquid crystal polymer, by a process comprising melt-mixing the polymer with high loadings of leachable glass and then leaching the glass from the polymer to leave a continuous relict polymer network, the network typically demonstrating pore volumes of 50 percent or more and average pore diameters in the 0.1-10 micron range.
