✦ Synopsis

The condensation reactions between tris(hydroxymethyl)phosphine, P(CH,OH),, and either 1 ,bdiaminohexane or the trifunctional polyetheramine Jeffamine T-403 produce polymeric aminomethyl phosphines containing excess NH, groups. These polymers, after oxidation to the phosphine oxides, can be used as supports for enzyme immobilization. Immobilised urease retains activity after continuing usage in urea solutions.
