Abstract
1293940 Polyurethane prepolymer dispersions ASAHI KASEI KOGYO KK 6 Nov 1969 [8 Nov 1968 19 March 1969] 54502/69 Heading C3R A polyurethane composition is prepared by dispersing in water an isocyanate groupcontaining polyurethane prepolymer based on a stoichiometric excess of an organic isocyanate and a polyol comprising a polyethylene ether moiety of a molecular weight of between 600 and 2500 and which is a percentage by weight of the polyol of at least 7À2-9 log P/100 (P being the molecular weight of the moiety), the said dispersion being effected in the presence of a sulphosuccinate-type anionic surface-active agent (S), a nonionic surface-active agent (N) having an H.L.B. value of from 6 to 16, and a compound (T) represented by the formula X-[-O-(CH 2 ) m -SO 3 Y] n , wherein X denotes an n-valent organic radical having a molecular weight of from 500 to 5000, Y denotes an alkali metal, m denotes 2, 3 or 4 and n denotes 1, 2, 3 or 4, the amount of S, N and T present being such that the percentages by weight of S, N and T, relative to the total weight of S, N and T, each percentage being plotted as one triangular co-ordinate, will not fall outside the area ABCDEA shown in Fig. 2. The H.L.B. value is stated to be one fifth of the weight per cent of the hydrophilic moiety of the surface-active agent. The dispersion may be carried out in the additional presence of a water-soluble compound containing at least 2 primary or secondary amino groups per molecule, e.g. hydrazine, aliphatic or aromatic polyamines and heterocyclic amines. The requisite polyol may be a compound containing a suitable polyethylene ether moiety or a mixture of compounds in which at least one component provides the said moiety. In examples polyurethane prepolymers suitable for dispersion are prepared from 4,4<SP>1</SP>-diphenylmethane-, 2,4-tolylene- and 1,6-hexamethylene diisocyanates, and from mixtures of polycaprolactone glycol (1200 or 1250) and polyethylene glycol (1000), polytetramethylene ether glycol (1380 or 2000) and polyethylene glycol (1200 or 1500), and polyethylene adipate (1250 or 1500) and polyethylene glycol (1000 or 1500), and from a copolymer (M.W. 2500) of epsiloncaprolactone and polyethylene glycol (800). The resulting polyurethane dispersions may be cast as films on to glass plates, aggregated to granular polyurethane by addition of sodium chloride and the resulting powder compression moulded into sheets or melted and extruded through nozzles to form filaments. Uses.-For admixture with addition polymer emulsions, for preparation of films, filaments and synthetic leathers, for coating fabrics, knits, leathers, papers, woods, and metals, for adhesives and wrinkle-resisting finishes, for blenders of concrete and mortar, for plasticizers and for blending agents for polymers. Compounds referred to as T (above) are specifically prepared by reacting polycaprolactone glycol (1200) with propanesultone and sodium hydroxide, or by reacting polytetramethylene ether glycol with propanesultone and sodium hydroxide.
