Exact spinning speeds and dimensions are specified. The use of different bore coagulants (water, glycerin, isopropyl alcohol) produces strong, weak or double-skinned membranes. Ultrafiltration capacities are indicated. - Chemical Abstracts, 112(18), 1990, abstract 160309 Korean Active skin layer formation control of microporous asymmetric polysulphone hollow fibre membranes Article 1 Hwahak Konghak, v.27, no.4, pp.595 - 601 Hwahak Konghak 27 4 595 601 scopus 2-s2.0-0024579926 Article active skin layer formation control
