Title: Improvements in the manufacture and production of synthetic substances
IPC: C08F16/36
Filed: 1936-09-11
Abstract: Methyl vinyl ketone is condensed with a water-soluble aldehyde or a substance acting as such.  Aldehydes specified are formaldehyde, paraformaldehyde, hexamethylene tetramine, methylal, acetaldehyde, paracetaldehyde, propionaldehyde, and furfural.  The reaction may be carried out in a neutral or slightly acid aqueous or inert water-soluble medium at ordinary or slightly raised temperature to give water-soluble products.  There may also be present substances which react with formaldehyde to give resinous products, e.g. phenols, amines, urea, cyanamide ; or methyl vinyl ketone may be condensed with methylol compounds of such substances, e.g. dimethylol urea or p-cresoldicarbinol. Resinous products are obtained by carrying out the reaction in a strongly basic medium, or by adding to the water-soluble product a substance having a strongly basic reaction, e.g. sodium, potassium, calcium, or barium hydroxide solution or strong organic bases such as methylamine, ethylene-diamine, tetramethylammonium hydroxide, piperidine, ethanolamines, benzylamine, or cyclohexylamine.  The water-soluble products may be used as adhesives, e.g. for glueing wood veneers by adding dilute caustic soda and brushing on.  The resinous products, to which fillers and dyestuffs may be added, may be used for electrical mouldings.  In examples: methyl vinyl ketone is condensed with a neutral solution of formaldehyde or acetaldehyde, condensed to a viscous syrup, and concentrated caustic soda added to precipitate the resin. Alternatively, wood meal may be added before precipitation and the mix moulded.

Patent GB-777793-A (GB)
Title: Improvements in the production of linear unsaturated polyesters
IPC: C08G63/553
Filed: 1955-09-05
Abstract: An unsaturated polyester is made by reacting (a) an unsaturated alpha, beta-dicarboxylic acid (e.g. maleic or fumaric) with (b) a diester of a polyhydric alcohol containing two carbocyclic rings and an endomethylene bridge and having the hydroxyl groups joined to nuclear carbon atoms with a monocarboxylic acid containing up to three carbon atoms.  Specified diesters are those of formul <FORM:0777793/IV(a)/1> and <FORM:0777793/IV(a)/2> in which R is hydrogen, methyl or ethyl.  Part of the unsaturated dicarboxylic may be replaced by a saturated dicarboxylic acid and part of the endocyclic diester may be replaced by a conventional diol (e.g. ethylene, diethylene, 1,3-butylene, 1.4-butylene, or 1,6-hexylene glycol).  Monocarboxylic acids and monohydric alcohols may also be included in the reaction.  The products may be copolymerized with styrene, alkyl styrenes, chlorstyrenes, vinyl naphthalene or vinyl acetate in presence of organic peroxides, redox systems (e.g. benzoyl peroxide + a tertiary amine) and, if desired, driers (e.g. cobalt naphthenate).  In examples maleic anhydride, phthalic anhydride, and a diformate corresponding to one of the above formul  were polycondensed in presence of butyl alcohol (which forms dibutyl formate with the acid split off from the diester), hydroquinone and trichloroethyl phosphorous acid ester.  The resulting polyester was then dissolved in styrene and methyl ethyl ketone peroxide dissolved in dimethyl phthalate and cobalt naphthenate added to form a coating composition.  If it is desired to apply the solution with a spray gun, there is added butanol, ethylene glycol acetate and additional styrene.  Specification 766,666 is referred to.
