摘要： 1364996 Elastomer blends CITIES SERVICE CO 31 Oct 1972 [26 Nov 1971] 50167/72 Headings C3P and C3Q A homogeneous blend of elastomers is produced by mixing an elastomer in latex form with an elastomer dissolved in an organic solvent to form a pseudoemulsion in which the two elastomers are mixed, at least partially coagulating the elastomer of the latex prior to coagulation of the dissolved elastomer, subsequently vaporizing organic solvent from the pseudomulsion, coagulating the dissolved elasomer in the presence of the coagulated elastomer from the latex and thus agglutinating the two elastomers. The at least partial coagulation of the elastomer latex may be effected by addition of a coagulating agent to the pseudoemulsion prior to any vaporization of the organic solvent, the pseudoemulsion then being diluted with hot water containing a coagulating agent so that the solvent evaporates and coagulation of the dissolved elastomer takes place. In one embodiment, shown in the examples, the partially coagulated pseudoemulsion is fed into a hot water bath containing sulphuric acid, a part of the hot water being recylced and mixed with the pseudoemulsion entering the bath. A carbon black slurry is mixed in the examples with a styrene-butadiene rubber latex. The mixture is creamed and added in a steam eductor to polybutadiene dissolved in toluene containing aromatic oil, the effluent being fed to the aforesaid hot water bath, from which water is circulated to the eductor.

摘要： 1,248,661. Moulds for casting cement. ELASTOMER ENG. Ltd., and EASICAST RUBBER MOULDS Ltd. 10 March, 1970 [13 March, 1969], No. 13285/69. Heading B5A. A mould used in casting cement or other cementitious material or a component or accessory of such a mould is characterized in that it is made from a vulcanized natural or synthetic rubber composition comprising an oil that is incompatible with the rubber base and has no significant affinity with the cement such that the oil leaches to the surface of the resilient material to provide a lubricating film. Suitable oils are castor oil and a polysiloxane oil.

摘要： The invention relates to microporous articles made of polymeric materials. Such articles may, in one example, be battery separators for electrical storage batteries. In one embodiment, the article comprises a microporous flexible shape or sheet of a sulfur-free, cured polymeric material of a curable rubber an ethylene-propylene copolymer or mixtures of the curable rubber and ethylene-propylene copolymer. The article possesses an average pore size of less than 2 microns, a predetermined flexibility, and improved toughness, when compared to prior art sulfur cured articles. A continuous production of the cured rubber base material has been found to be especially advantageous.

摘要： A vulcanizable composition having an improved tear strength comprises natural rubber, cis-polybutadiene, a filler as reinforcing agent, and an aliphatic amine. Suitable fillers are carbon and silica and suitable amines include dodecylamine, octadecylamine, dihydroxy ethyl octodecylamine, sec-heptylamine, and N,N-bis(isobutoxymethyl)-n -dodecylamine. Part of the natural rubber may be replaced by cis-polyisoprene.
