Abstract

Biological membranes are prepd. by depolymerising a biological polymer (pref. elastin degraded by hydrolysis, enzymes or organoalkaline) to give macromolecules which are then copolymerised, pref. with collagen, gelatin or protesglycarine etc. The membranes are used in filtration osmosis etc. for surgical, radical etc. applications, and as supports for catalysts and as catalysts.
