Abstract
A filter comprising a polymer material comprising a polymer matrix such as polyacrylonitrile containing dispersed metal oxide particles. The metal oxide particles are for example ferric oxide particles, and the polymer material contains generally 0.25-3% by weight of these particles. The filters are resistant to thermo-oxidation and have reduced shrinkage or degradation.
