Revista de Metalurgia (Madrid), 32(5), 298-302 (English) 1996 Centro Nacional de Investigaciones Metalurgicas.In this article, certain chemicals are used. Some of their cas registry numbers are 7423-42-9 and 13463-40-6 CODEN: RMTGAC. ISSN: 0034-8570. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) The exptl. equipment designed for obtaining iron and graphite nanoparticles in argon plasma, the building mechanisms of particles as well as the exptl. results on Fe(CO)5 and 2-ethyl-hexyl-iron maleate dissocn. by plasma jet are presented. The dimensions of the metal particles obtained range from 30 to 200 ?, while the graphite particles vary form 30 to 100 ?. .

High green strength emulsion rubbers by the use of half esters of unsaturated dicarboxylic acids

High green strength emulsion rubbers by the use of half esters of unsaturated dicarboxylic acids. Jalics, George (Goodyear Tire and Rubber Co. , USA). Eur. Pat. Appl. EP 95996 A2 7 Dec 1983, 21 pp. DESIGNATED STATES: R: DE, FR, GB, IT. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C08F236-04; C07C069-593. APPLICATION: EP 83-630090 20 May 1983. PRIORITY: US 82-382543 27 May 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 23 A process for improving green strength of emulsion polymn.There are some reagents with their cas registry numbers 1314-13-2 and 7423-42-9 are used in this study. rubbers comprises copolymg. a monomer or monomers with 1-10 wt. parts per 100 parts monomer of dicarboxylic acid deriv. and compounding the copolymer with 1-5 parts of a divalent metallic compd. selected from the group of Zn, Mg, and Ca, wherein the deriv. is a half ester or a half amide. Thus, mono(2-ethylhexyl) maleate (I) [7423-42-9] was prepd. by esterification of maleic anhydride with 2-ethylhexanol at 140°. A butadiene-I copolymer was prepd. by copolymn. of 95.00 wt. parts butadiene with 5.0 wt. parts I in an aq. soln. in presence of catalysts and surfactants at 10°. The butadiene-I copolymer was compounded with carbon black 50, tackifier 4.75, processing oil 17.25, stearic acid .50, and ZnO 3. The compounded copolymer had 100% modulus 89-104 psi, 300% modulus 161-182 psi, 500% modulus 220-237 psi, strength to break 218-280 psi, and elongation to break 450-720%, compared with 44-54, 36-72, 83-102, 117-165, and 740-980, resp., for a control contg. 0% I. .
