Title: Polyalkylene ether-polyurethane polymer and elastomeric products obtainable therefrom
Inventor: JR FREDERICK B HILL
IPC: C08G18/48
Filed: 1954-06-15
Abstract: In a process for making an elastomeric polyurethane by reacting under substantially anhydrous conditions a polyalkylene ether glycol of molecular weight at least 750 with a molar excess of a diisocyanate and reacting the product with a chain-extending agent (other than water) having a plurality of active hydrogen atoms, the reaction between the polyglycol and the diisocyanate is effected in presence of an acid-reacting substance whereby undesired gel formation is avoided.  The acid-reacting substance may be an acid chloride, bromide or iodide or an inorganic acid. The polyglycols and diisocyanates and substances with which the elastomer may be compounded are as specified in Specification 796,041.  The chain-extending agent may be hydrogen sulphide or an organic compound containing a plurality of active hydrogen atoms in the form of -OH, -SH, -NH-, -NH2, -COOH, -CONH2, -CONHR (where R is an organic radical), -SO2OH, -SO2NH2 or CSNH2 groups. Specified organic compounds are ethylene glycol, hexamethylene glycol, diethylene glycol, hydroquinone, adipic acid, terephthalic acid, succinic acid, adipamide, succinamide, 1,2-ethanedithiol, monoethanolamine, p-aminophenol, 4-aminobenzoic acid, aminopropionic acid, m-phenylene diamine, propylenediamine, ethylenediamine, 2,4 - tolylenediamine, bis - (4 - aminophenyl) - methane, 4 - aminobenzamide, sulphanilamide, or 1:4-cyclohexanedisulphonamide, 1,3-propanedisulphonamide, 1,4-butanedisulphonamide, 4-hydroxybenzoic acid, beta-hydroxypropionic acid and 1,2-ethanedisulphonic acid.  The molar ratio of diisocyanate to polyglycol is preferably 1.1:1 to 12:1 and that of chain-extending agent to polyglycol is preferably 9:1 to 1:9.  If all of the isocyanate groups have been used up by reaction with the polyglycol and the chain-extending agent, the product is cured with additional diisocyanate or triisocyanate or other curing agent (e.g. magnesium oxide) otherwise the product may be cured by heating alone.  An uncured elastomer containing free isocyanate groups may be stabilized by addition of a nitrogen base (e.g. pyridine or piperidine).  Reaction between the polyglycol and diisocyanate may be accelerated by addition of a phosphorus or tertiary nitrogen base.  In examples, polyethylene glycol is heated with 2,4-tolylene diisocyanate or 4,41-methylene-bis-(phenylisocyanate) in presence of benzenesulphonyl chloride and the product heated with pyridine and m-tolylenediamine or m-phenylenediamine to produce an elastomer which is cured by heating with 2,4-tolylene diisocyanate or 4,41-methylene-bis-(phenylisocyanate).  Specification 791,852 also is referred to.

Title: Improvements in the manufacture and production of organic sulphur compounds
IPC: C07C317/14
Filed: 1935-02-15
Abstract: Organic sulphur compounds are manufactured by reacting vinyl sulphones of the general formula R(SO2CH=CH2)x where R is an isocyclic or heterocyclic radicle and x is a whole number, with bisulphites of light metals.  Suitable vinyl sulphones are those in which R is an isocyclic radicle such as that of benzene, toluene, naphthalene, anthracene, phenanthrene, anthraquinone or benzanthrone or another polynuclear isocyclic compound, e.g. phenyl, tolyl, b -naphthyl or 1-chloro-8-naphthyl vinyl sulphone, or in which R is a hydroaromatic radicle such as that of cyclohexane or tetrahydronaphthalene, or a heterocyclic radicle such as that of pyridine, quinoline, benzothiazole or benzimidazole, or in which the cyclic radicles are combined with the sulphone groups by means of aliphatic groups, e.g. phenylmethyl or phenylethyl vinyl sulphone. The sulphones may contain more than one vinyl sulphone group, and may contain substituents, e.g. halogens or hydroxy, alkyl, alkoxy, hydroxyalkyl, nitro, amino, carboxylic or sulphonic groups.  The reaction is preferably carried out in the presence of solvents or diluents, e.g. water or aqueous alcohol, if desired under pressure. The products may be used for the preparation of dyestuffs, in some cases as dyestuffs themselves, or as assistants for the textile and related industries.  In examples: (1) vinyl-p-tolyl sulphone is refluxed with aqueous sodium bisulphite, yielding a product of the probable formula CH3C4H4SO2CH2CH2SO3NA, from which the corresponding barium salt may be produced by the action of barium chloride or hydroxide; (2) vinyl-b -naphthyl sulphone similarly yields a product of the probable formula <FORM:0450559/IV/1> (3) vinyl-p-tolyl sulphone is reacted with a solution obtained by supersaturating aqueous sodium carbonate with sulphur dioxide, yield a product of the probable formula CH3C6H4SO2 CH2CH2SO3Na; (4) a mixture of magnesium sulphite solution and vinyl-p-tolyl sulphone is supersaturated with sulphur dioxide, to yield the corresponding magnesium salt; (5) vinyl-p-tolyl sulphone is reacted with a solution obtained by supersaturating a mixture of calcium oxide and water with sulphur dioxide, yielding the corresponding calcium salt; (6) benzene-m-divinylsulphone (obtained by oxidizing the corresponding disulphide by means of hydrogen peroxide) is heated with aqueous sodium bisulphite to yield a product of the probable formula <FORM:0450559/IV/2> Specification 442,524 is referred to.
