Low density, polybutadiene-based, wet filament winding resin

Low density, polybutadiene-based, wet filament winding resin. Valentine, Robert H. (Hercules Inc. , USA). U.S. US 4499240 A 12 Feb 1985, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: C08F008-00. NCL: 525193000. APPLICATION: US 83-554665 23 Nov 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) A wet filament winding resin having viscosity 1000-5000 cP at 20-60°, d. <1.05 g/cm3 after curing, and pot life 34 mo at 25° comprises polybutadiene (I) having no.-av. mol. wt. 10,000-40,000 and 1,2-vinyl content 50-95% (based on total unsatn.), I having no.-av. mol. wt. 100-2500 and 1,2-vinyl content 1-95%, an unsatd. monomer having lower viscosity than the crosslinkable polymer component, and a peroxide-free radical initiator having half-life 10 h at >55°. Thus, a resin compn. consisting of I (mol. wt. 14,000) 100, butadiene rubber 15, tert-butylstyrene [25338-51-6] 100, tetraethylene glycol dimethacrylate [109-17-1] 15, isobornyl methacrylate [7534-94-3] 45, tert-Bu perbenzoate [614-45-9] 2.75, and 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane [78-63-7] 4.13 parts was used in the manuf of a wound pressure bottle having diam. 6 in. and bursting pressure 3475 psi.

Kokai Tokkyo Koho JP 03294374 A2 25 Dec 1991 Heisei, 5 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C09J004-02. ICS: C09J175-04.Some commonly used reagents like 7534-94-3 and 99-97-8 are used in this experiment. APPLICATION: JP 90-96877 12 Apr 1990. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 37 The title compns., useful for bonding polyether-polysulfone films to polycarbonate sheets, comprise a mixt. of 20-40% polyester-polyurethanes and 60-80% epoxy acrylates or alternatively of 10-30% polyester-polyurethanes, 45-75% epoxy acrylates, and 5-35% isobornyl methacrylate 100, camphorquinone 0.1-2.5, benzoyl peroxide 0.05-0.3, and tertiary amines 0.2-2.5 parts. Thus, a compn. of adipic acid-ethylene glycol-TDI copolymer 30, 2-hydroxy-3-phenoxypropyl acrylate 70, camphorquinone 0.5, benzoyl peroxide 0.25, and N,N-dimethyl-p-toluidine was applied to a polyether-polysulfone film, pasted to a polycarbonate sheet, placed between two glass plates, and irradiated from the polycarbonate side with a metal halide lamp (6000 mJ/cm2). The laminate was transparent and showed 180° angle peel strength 1.0 kg/in. vs. 0.2 for a control bonded with a mixt. of Araldite CY 175 20, Araldite CY 177 80, and Irgacure 261 2.0 parts. .
