Tough epoxy polymers formable by reaction injection molding. Salloum, Robert J.; Atkins, Richard P. (General Motors Corp., USA). U.S. US 4497945 A 5 Feb 1985, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: C08G059-42. ICS: C08G059-62; C08J005-00. NCL: 528094000. APPLICATION: US 83-505706 20 Jun 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Impact-resistant epoxy compns. that can be reaction-injection molded consist of bisphenol A-epichlorohydrin copolymer (I) [25068-38-6] and an anhydride-terminated polyoxypropylenediol or triol crosslinking agent. For example, Pluracol 2010 [25322-69-4] 44, hexahydrophthalic anhydride [85-42-7] 68, and 1-methylimidazole 1 part were heated 6 h at 150° to give polypropylene glycol bis(hexahydrophthalate) [51024-14-7], which was heated to 115°, mixed with 5 phr 2-ethyl-4-methylimidazole, mixed rapidly with I heated to 115°, and molded at 115° to give samples having tensile strength 40 MPa, Young's modulus 1540 MPa, elongation 17.8%, toughness 6.27 MPa, time to peak exotherm 180 s, and peak temp. 122°.

Lubricant

Lubricant. Roth, Ludwig (Roth, Carl, G.m.b.H. und Co., Fed. Rep. Ger.). Ger. Offen. DE 3322432 A1 3 Jan 1985, 8 pp. (German). (Germany). CODEN: GWXXBX. CLASS: ICM: C10M003-18. ICS: C10M003-16; C10M007-20; C10M007-12; C10M007-30. APPLICATION: DE 83-3322432 22 Jun 1983. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) A stick-shaped lubricant (e.g., for household use) consists of NH4 myristate [16530-71-5], a thickener, and a binding agent. Examples of thickeners include paraffin oil, petrolatum, a polyoxyalkylene (poly(ethylene glycol) [25322-68-3] or poly(propylene glycol) [25322-69-4]), and poly(vinylpyrrolidone) [9003-39-8]. Suitable binding agents include cetyl alc. [36653-82-4], adipic acid [124-04-9], and oleyl alc. [143-28-2].
