摘要： The invention comprises a 3,31-methylenebis (4-aliphatic-oxyaniline) in which each aliphaticoxy group contains 3 or more carbon atoms, and a process for its preparation by condensing the appropriate aliphatic-oxy aniline with formaldehyde (or a formaldehyde precursor) in presence of an acid catalyst. The preparation of 3,31-methylene bis (4-n-heptyloxyaniline) by this method is exemplified. Other methods mentioned are reduction of the product of condensing an aliphatic-oxy nitrobenzene with formaldehyde or with an aliphatic-oxy nitrobenzyl chloride. A number of specific compounds within the scope of the invention are listed.ALSO:A vulcanisable rubber composition is characterised by the presence of sulphur or a sulphur-containing vulcanising agent, and a methylene bis (aliphatic-oxyaniline), e.g. 3,31-methylenebis (2-, 4- or 6-ethoxyaniline); 3,31-methylenebis (4-methoxyaniline); or 3131-methylenebis (4-n-heptyloxyaniline). The preferred sulphur-containing agent is a benzthiazylsulphonamide e.g. N-cyclohexyl -2- benzthiazylsulphonamide. Examples describe the vulcanisation of natural rubber, styrene-butadiene and cis-1, 4-polyisoprene.

摘要： 1,180,269. Accelerator combinations. MONSANTO CHEMICALS Ltd. 27 Sept., 1968 [20 Oct., 1967], No. 47900/67. Heading C3E. An accelerator combination for rubber vulcanization comprises (a) a benzothiazyl sulphenamide accelerator or mixture thereof and (b) a thiuram disulphide accelerator or a zinc dithiocarbamate accelerator or a mixture thereof, the weight ratio of a : b being between 65 : 35 and 35 : 65. Accelerators used are N- cyclohexyl- and N-tert.butyl-benzothiazyl sulphenamide, tetramethyl and tetraethyl thiuram disulphide, and zinc dimethyl and diethyldithiocarbamate. In one example a mixture of N-tert. butyl benzothiazyl sulphenamide, TMTD and ZDC is used.

摘要： The invention comprises aliphaticoxycarbonylmethylene bis (dithiocarbamate) compounds of the formula where R1 and R11 are each an alkyl group and R is an alkyl group containing at least 4 carbon atoms or where (R1)(R11)N- represents an alkylmorpholino group and R is an alkyl group. They may be obtained by reacting a salt, preferably an alkali metal salt, of the appropriately substituted dithiocarbamic acid with an ester of a dihaloacetic acid, for example dichloracetic acid. The reaction is generally effected between 50 and 120 DEG C. in an inert solvent which may be aqueous but is preferably organic, e.g. acetone which may contain a small amount of water, dimethylformamide or an alcohol, the alkyl radical of the alcohol preferably being the same as the alkyl group esterifying the dihaloacetic acid. Where R1 and R11 are each alkyl and R is an alkyl group containing four or more carbons, R1 and R11 are preferably straight chain alkyl containing up to 4 carbons and R is preferably C4- 14 alkyl having either a straight or branched chain. Specified new compounds are neopentyl-, n-heptyl- and 2-ethyl hexyl - oxy carbonyl methylene bis (N,N - dimethyldithiocarbamate), n - hexyl oxycarbonyl methylene - bis (N,N - diethyldithiocarbamate) and methyl bis [2,6-dimethylmorpholino (thiocarbonyl) thio] acetate. The products have applications as delayed action accelerators in the vulcanization of natural and synthetic rubbers (see Division C3).

摘要： Vulcanisation of diene rubber using S is carried out with accelerator combination of (a) benxothiazole sulphenamine (s) and (b) thiuram disulphide and/or Zn dithiocarbamate in 65:35 to 35:65 wt. ratio for a:b. It is possible to adjust scorch retardation and modulus of vulcanisate to values obtained with activated thiazole accelerator and produce higher vulcanisation rate. Much less accelerator is necessary, so that total costs can often be reduced, in spite of higher unit costs.
