Abstract
A heat-treated condensation product is obtained by heating bis-1,4-(2,6-dimethylol-4 methyl phenoxy)butene-2 (see Group IV(b)) in the presence of an acid catalyst. Acid catalysts mentioned are sulphuric, hydrochloric and p-toluene sulphonic acids. Sulphamic acid in methanol is employed as catalyst in the example. The product is useful in moulding and laminating operations. Fillers mentioned include wood flour, asbestos flakes and glass fibres and dyes and pigments may also be incorporated in the molten phenoxy butene derivative.ALSO:The invention comprises bis-1,4-(2,6-dimethylol-4-methylphenoxy)butene-2. The compound is prepared by heating in acetone a mixture comprising 2,6-dimethylol-4-methylphenol and 1,4-dichlorobutene-2 in the presence of potassium carbonate and thereafter isolating the desired compound. A heat-treated condensation product is obtained by heating bis-1,4-(2,6-dimethylol-4-methylphenoxy)butene-2 in the presence of an acid catalyst (see Group IV (a)). In the example 2,6-dimethylol-4-methylphenol, prepared by mixing p-cresol dissolved in aqueous sodium hydroxide with aqueous formaldehyde and maintaining the mixture at a slightly elevated temperature and acidifying the sodium salt produced, is refluxed with 1,4-dichlorobutene-2 and potassium carbonate in the presence of acetone to obtain the desired product which is recrystallized from toluene. The phenoxy butene derivative is treated with sulphonic acid in methanol to obtain condensation products.
