Abstract: A heat-hardenable non-gelled resin soluble in organic solvents comprises an interpolymer of (A) an amide of an ethylenically unsaturated carboxylic acid, and (B) ethylenically unsaturated material copolymerizable with the amide, the interpolymer having amido hydrogen atoms at least partially replaced by the structure. <FORM:1012485/C3/1> where R represents hydrogen or a furyl, aromatic or saturated aliphatic hydrocarbon radical containing up to 10 carbon atoms, and R1 represents hydrogen or the etherification residue of an aliphatic alcohol containing up to 10 carbon atoms, and hydroxy-terminated organo-silicon resinous material condensed on to a side chain of the interpolymer.  The non-gelled resin may be obtained by condensing the silicone resinous material on to a side chain of the interpolymer, before, after or simultaneously with interpolymer formation.  Lists of monomers (A) and (B) are given; the preferred monomer (A) is acrylamide and the preferred monomer (B) carries a hydroxyl group, e.g. alcohols, hydroxy-esters, ethers and unsaturated polyesters may be used. In addition to monomers (A) and (B), monomers (C) containing a CH2=C< group, but which are not reactive with the hydroxy group of the silicone resin, may be included in the interpolymer. The preferred silicone materials are organo siloxanes produced from organo silanes containing at least two hydrolysable substituents, which silanes have the formula RySiXz in which X is a halogen or a hydrolysable radical -OR1, and in which R and R1 are monovalent aliphatic, aromatic, alicyclic or heterocyclic radicals, y is 1 or 2 and z is 2 or 3. Preferably the polymerization of the silane diols or triols formed from the silanes is stopped before complete condensation and the intermediate formed is used as the silicone resinous material. The replacing of the amido hydrogen atoms of the interpolymer by the structure <FORM:1012485/C3/2> may be carried out simultaneously with the polymerization by polymerizing in the presence of an aldehyde or aldehyde-releasing substance. The non-gelled resins of the invention may be used in organic solvent solution coating compositions alone or in the presence of ureaformaldehyde condensates, melamine-formaldehyde condensates, or the butylated derivatives of either of these, condensates of aldehydes with triazines such as benzoguanamine, alkyd resins, epoxy resins and vinyl resins; preferably hexamethylol melamine, hexamethoxymethyl melamine or hydroxy containing copolymers such as vinyl chloride/vinyl acetate copolymers which have been partially hydrolyzed or saponified, are used.

Filed: 1949-06-23
Abstract: Cleansing compositions comprise at least 60 per cent of soap and a minor proportion, e.g. 2-10 per cent, of magnesium silicate colloidally soluble in water, with or without a synthetic soap substitute and other additions ordinarily included in cleansing compositions, the incorporation of solvents, oxygen-yielding substances, soda and substances more alkaline than soda being, however, excluded.  The magnesium silicate has the effect of reducing the deposition of insoluble substances on the material to be treated. Specified optional additions are sodium pyro-, tri- or hexaphosphate, glue, gelatine, glycerine, polysaccharide derivatives, plant mucilages and urea- or phenol-aldehyde condensation products; sodium silicate is preferably not included.  The molecular ratio of magnesia to silica in the magnesium silicate preferably lies within the range 1 : 1-3 : 2. The compositions may be produced in the form of powders or in shaped forms such as bars, strips, ribbons, nodules or flakes, and may be used for washing clothes or as body-cleansing agents or shampoos.  In examples, (1) sliced soap is mixed on flaking rollers with sodium pyrophosphate and magnesium silicate of antigorite type; (2) sodium metasilicate is added to magnesium chloride solution to produce a suspension of magnesium silicate, to which sodium tripolyphosphate, dodecyl benzene sulphonate and sulphonate and soap are added in turn; the product is then spray-dried to yield a powder which can be used as such or worked into flakes.
