Abstract
The occlusion structure is composed of microporous structures or polymer solns. producing them. Prods. can be mfd. from which the occluded substances can be discharged progressively over a given period of time, or not discharged at all, when placed in contact with a reactive medium. In an example, coloured paper can be mfd. by adding coloured microfibres to the pulp, thus abviating water-pollution problems. Microfibres contg. medicaments, antiseptics, pesticides, microorganisms, etc. can be prepd. to liberate the active components are desired, etc. Process is also used for the treatment of waster waters.
