Abstract
Polymeric amines, e.g. gelatine, watersoluble collagens, isinglass, eucollagens, zein, casein, albumin, soya bean protein, peptides, polyalkylene imines and polyvinylamines are converted into water-soluble reactive compounds by reacting them with a di- or polyfunctional reagent under controlled reaction conditions so that a water-insoluble network is not formed. The conditions are chosen from one or more of the following:- (a) For medium grade gelatines, the proteins are reacted in an aqueous solution of not above 15% w./w. (b) The reaction is carried out in mildly acid to neutral media (pH 4.2 to 7.0) which are adjusted to pH 8 to 9.5 in the final stages. (c) The temperature is mantained above a lower limit, e.g. 35 DEG C., such that natural gelation will not occur. (d) At least one molecule of the polyfunctional reagent per amino group is provided or the polymeric amine is reacted with a monofunctional reagent prior to, simultaneously with or subsequent to reaction with the polyfunctional reagent. Suitable polyfunctional reactants are halogeno-s-triazinyl and halogenopyrimidyl derivatives. Suitable monofunctional reactants are organic acid anhydrides and acid halides, e.g. sulphonyl chlorides, benzoyl chloride, lauroyl chloride, 2,4-dinitro-1-fluorobenzene and isothiocyanates, e.g. phenyl isothiocyanate.
