Abstract: Prepn. of dialkyl thiodipropionates of formula (R1OOC.CH2CH2)2S (I) comprises reacting H2S and acrylate esters H2C=CH.COOR1 (II) in presence of phenolates R2R3C6H3OZ (III) as catalysts. In the formulae each Ru is aliphatic gp. R2 and R3 are each aliphatic or aromatic gp., OH, OZ or alkoxy. Z=alkali metal). Also new is the use of (I) in which R1 are both 4-9C alkyl (cpd. (Ia)) as low-temp. stable plasticisers for rubbers (natural or synthetic). They are used at 0.5-100 wt. % on the rubber. Apart from use as plasticisers, (I) are intermediates for dyes, pesticides, and rubber auxiliaries, and are anti-oxidants for fats and oils. Better yields and purity are obtd. (II) does not add across the double bond of (II) unlike alkoxide catalysts previously proposed.

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 polycondensates are made by condensing isobutyraldehyde (I) with a phenol (II) in a ratio (I)/(II) of 0.6-0.9:1, in the presence of an acid catalyst comprising a phosphorus halide, H2SO4, an aromatic acid or HCl. Excess (I) is then distilled off. The reaction is carried out either by adding the (I) gradually to the (II) according to the conversion, until excess (I) has been added, or the (I) and anII) are added simultaneously to the reactor or are previously mixed. Use of the stated catalysts and conditions allows poly-condensates of (I) and (II) to be made without the formation of large amts. of low molecular material, as in previous processes. The prods. are useful tackifiers in unvulcanised (natural)rubber, as components in adhesives, as sand core binders and as binders for wood fibre boards.

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: 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.
