Abstract
A resin made from 1-hydroxy-3 : 5-dimethyl benzene, 1-hydroxy-2 : 4-dimethyl benzene, a bifunctional xylenol and formaldehyde is agitated with methanol-methyl acetate, epichlorohydrin and a polyvinyl alcohol solution to form an emulsion which is mixed with hydrochloric acid, applied to glass plates and dried. Specification 757,202, [Group IV (a)], is referred to.ALSO:Liquid resins capable of being hardened are made by condensing an aldehyde, with a mixture of monohydric mononuclear phenols comprising 30% to 90% by weight of 1-hydroxy-3 : 5-dimethylbenzene, 5% to 25% by weight of a monofunctional xylenol and 5% to 65% by weight of o- or p-cresol or a bi-functional xylenol. Specified aldehydes are formaldehyde and acetaldehyde. The resins may be modified by reaction with chlorinated organic compounds containing oxygen, e.g. 1 : 2 or 1 : 3 dichloropropanol, monochloropropanol, glycol chlorhydrin, epichlorohydrin, dichlorotertiary isobutanol, chloral hydrate, b -dichloropropionaldehyde hydrate, chlorobenzaldehyde and chlorinated phenol, cresol, naphthol or xylenol or with phosphoric acid esters containing up to six carbon atoms, e.g. trimethyl phosphate and methyl phosphate and mixtures thereof with furfural. The resins may also be worked up with hardening agents, e.g. 1 : 5-naphthalene disulphonic acid, p-toluene-sulphonic acid, p-toluene-sulphochloride, maleic acid anhydride, hydrochloric acid, phosphoric acid, sulphuric acid, benzotrichloride and lead oxide. The resins may be mixed with fillers, e.g. silicon, silicon carbide, graphite, silica, quartz, titanium dioxide, barium sulphate, phenol-aldehyde resins, polyvinyl chloride, polytetrafluorethylene, polytrifluorochlorethylene or partially acetalized polyvinyl alcohol or may be emulsified by introduction into an aqueous solution of polyvinyl alcohol. In examples: (1) and (2) resins are made from 1-hydroxy-3 : 5-dimethyl benzene, a bi-functional xylenol 1-hydroxy-2 : 6-dimethyl-benzene and formaldehyde; (3) the product of Example (1) is cured with chlorobenzene and ethylene chlorohydrin in the presence of quartz powder and polyvinyl chloride and optionally p-toluene sulphonic acid; (4) the product of Example (1) is agitated with methanol-methyl acetate, epichlorohydrin and a polyvinyl alcohol solution to form an emulsion which is mixed with hydrochloric acid, applied to glass plates and dried; (5) the product of Example (2) is mixed with graphite and moulded. Specification 757,202 is referred to.
