The amine treatment of phosphorylated wool (phosphorus trichloride followed by basic hydrolysis) with either N-methylamine or tetraethylenepentamine gave a product which had marked shrink-resist properties, N-methylamine being the more effective reagent. The shrink-resist properties of the N-methylamine-treated wool was increased by Basolan polymer application with minimal fabric shrinkage being obtained with a 1.0% Basolan application; increased shrinkage occurring with decreasing levels of Basolan. From studies which used polystyrene residue with bound synthetic peptides as model substrates, the data obtained suggested that the secondary modification procedure possibly proceeded via base-mediated β-elimination of the phosphorylated seryl (and threonyl) residues followed by amine addition to the resultant dehydroalanyl residue to give an amino side-chain amino acyl residue.
