Diacyl peroxide composition

Diacyl peroxide composition. Katoh, Kenji (Nippon Oils and Fats Co., Ltd. , Japan). Eur. Pat. Appl. EP 133514 A1 27 Feb 1985, 33 pp. DESIGNATED STATES: R: DE, FR, GB, NL. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: ICM: C07C179-15. ICA: C08F004-38. APPLICATION: EP 84-108765 25 Jul 1984. PRIORITY: JP 83-142593 5 Aug 1983; JP 83-202705 31 Oct 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 35 The title compn. comprises 40-90 parts solvent and 10-60 parts peroxides comprising 1-40% Bz2O2 [94-36-0], 5-79% peroxide selected from di-o-toluoyl peroxide [3034-79-5], di-m-toluoyl peroxide (I) [1712-87-4], m-toluoyl o-toluoyl peroxide [96662-03-2], and a mixt. thereof, and 20-55% peroxide selected from Bz m-toluoyl peroxide (II) [96662-04-3], Bz o-toluoyl peroxide [3901-08-4], and a mixt. thereof. The peroxide compn. is resistant to deposition of solids and to phase sepn. during cooling below -5°, has good handling properties and storage stability, and is useful as a curing agent for unsatd. polyester resins, etc. Thus, 480 g 10% NaOH soln. was mixed with 40.8 g 50% aq. H2O2 and 100 g xylene, treated slowly at 25° with a mixt. of 0.2 mol BzCl and 0.8 mol m-toluoyl chloride, and stirred 1 h. The org. phase was sepd., washed with water, and dried with 20 g MgSO4 to give 210.2 g soln. contg. 56.6% 5: Bz2O2-I-II mixt. During 6 mo of storage in a sealed container, the mixt. retained 100, 94, and 77% of its active O, resp., when the storage temp. was -5, +5, and +15°, resp. The catalytic activity of the soln. was similar to that of a Bz2O2-dioctyl phthalate mixt. in the curing of an unsatd. polyester resin.

CODEN: JKXXAF. CLASS: ICM: C09J004-02. ICA: C08F002-44; C08K007-08. APPLICATION: JP 90-65626 16 Mar 1990. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 38 The title compns., showing a long pot life at high temp. and humidity and suitable for rapid bonding, contain (meth)acryloyl group-contg. monomers 100, org. peroxides 0.2-10, reducing agents 0. 1712-87-4 and 109-16-0 which are cas registry numbers are also used here.1-5, and K titanate fibers 0.1-50 parts. An emulsion prepd. from poly(vinyl alc.) (86% sapond.; d.p. 1400) 100, NK Ester BPE-200 1000, and water-sol. Me2NH-substituted nylon 20 g was mixed with TISMO-D, 7 parts dimethyl-p-toluidine, and 40 parts Bz2O2-contg. capsules formed by treating a prepolymer of 37% HCHO 350, urea 131, and Et3N 1.7 g with 12.8 g Bz2O2. The mixt. was used as an anaerobic adhesive for bonding the heads of chromated metal screws and stainless steel screws to metal surfaces. .
