Abstract
1389276 Phosphorus-containing condensation products CIBA GEIGY AG 5 Sept 1972 [14 Jan 1972] 41095/72 Heading C3R [Also in Division D1] Condensation products are obtained by condensing 1 mol. of a tetrakis-(hydroxymethyl)- phosphonium compound with 0À02 to 1 mol. of an optionally methylolated compound of formula where R is alkoxy, hydroxyalkoxy, aminocarbonyl or a radical where Z is >N-, >P- or >P=O, at 40 to 120 C., optionally with formaldehyde or a formaldehyde-donating agent and optionally in the presence of a solvent. Optionally the condensation may be continued at 100 to 150 C. and free hydroxyl groups in the condensation product may be etherified. Organic fibre materials may be flameproofed by applying to them aqueous compositions containing the condensation products together with polyfunctional epoxides or nitrogen compounds, and then curing by heating the materials either when dry or while still moist or by contacting them with ammonia. In examples tetrakis-(hydroxymethyl)phosphonium chloride and hydroxide are condensed with oxalic acid diamide, hydroxyethylcarbamate, N-dimethylol-methylcarbamate, methylcarbamate and formaldehyde, and #,#
