Abstract: Isobutyraldehyde-phenol polycondensates of novolak type are prepd. by reacting isobutyraldehyde with a phenol in mol. ratio of 2-0.5:1 (0.8-1.3:1) in the presence of a strong inorganic acid or a Lewis acid. Process takes place in the melt, in absence of solvents. The polycondensates are used as adhesive agents for rubber. Other uses are: prepn. of adhesive mixts., wood glues, esp. binders for chipboard; sand core binders; and anti-ageing additives. Yields are quantitative. Tackiness improvement, partic. in natural rubber, is higher than that achieved with standard tackifiers, e.g. coumarone-, hydrocarbon- and known phenol resins.

Abstract: The use of 1,2,3,4-tetrahydro-4-anilino-3-ethyl-2- methylquinoline (I) as rubber additive is claimed. In an example a blend of 100 pts. smoked sheets, 40 pts. C black, 3 pts. aromatic plasticiser, 0.75 pt. paraffin, 1.5 pts. stearic acid, 5 pts. ZnO, 2.5 pts. S and 1 pt. benzothiazyl-2 -cyclohexylsulphenamide was treated with no antioxidant or with 3 pts. phenyl-beta-naphthylamine, 2,2'-methylene-bis (4-methyl-6-tert.-butylphenol) (II), 2,2,4-trimethyl-1,2- dihydroquinoline or (I). (I) was generally about as effective as (II) and more effective in the Mooney scorch test. (I) is an excellent stabiliser, esp. against thermal ageing, and is readily available.

Abstract: Isobutyraldehyde-phenol novolak condensates, (I), having mol. ratio aldehyde: pneol >1, are prepd. by adding the phenol to excess isobutyraldehyde in the presence of a P halide, H2SO4, an aromatic sulphonic acid or HCl, as acid catalyst. Phenol addn. advantageously takes place in proportion to conversion. The resin is pref. neutralised, esp. with NH3, before removing excess isobutyraldehyde, to prevent the formation of decompsn. prods. (I) are pref. used as tackifiers esp. for natural rubber and as chipboard binders; and may also be used in the prepn. of adhesive mixts., wood glues, sand core binders and as age-protective agents. Repeatable prepnd. results are achieved. On use as tackifiers, (I) highly increase adhesive power.

Abstract: Condensation products of aniline, a phenol or alkylated phenol and an aldehyde, especially formaldehyde, may be used as tackifiers and aging retardants for rubber, especially natural rubber.

Abstract: Prepn. of novolaks comprises reaction of an alkyl phenol with acetaldehyde in a mol. ratio of 1:0.3 to 1:1.5 in the presence of an acid catalyst. The alkyl phenol, in the absence of solvent, is mixed with catalyst and acetaldehyde is added continuously or intermittently so that the pressure is not >5 bar, until the desired mol. ratio is reached. The liq. reaction prod. are removed by heat and/or reduced pressure. The customary use of azeotropic distillation for water removal is omitted and no solvent recovery is involved. The procedure is simplified, yield is higher and effluent problems are diminished.
