Patent number: 4803231Abstract: Coherent thermoplastic aggregates with very high content of pulverulent mineral materials, said aggregates comprised of the said mineral materials, further of polyolefin polymers and/or copolymers, and possibly additionally of miscellaneous known additives; characterized in that, with the aim of achieving a density near to or at most equal to the theoretical density of the pulverulent mineral materials entering into their composition, while still having excellent compatibility with the polymers of redispersion, i.e., the polymers into which the subject aggregates are to be mixed, the interparticle voids between the grains of the mineral materials, which grains are basically in contact with each other, are at most filled--in the presence of a fluidifacient agent--by at least one polyolefin polymer and/or copolymer having a fusion temperature and/or softening temperature at least equal to 60.degree. C., and having a fluidity index (ASTM 1238) of at least 50.Type: GrantFiled: October 29, 1985Date of Patent: February 7, 1989Assignee: Pluess Staufer A.

Patent number: 4767812Abstract: An article for the sustained release of an insecticide into the ambient air comprises an elastomeric matrix, with the insecticide dissolved in the matrix. The matrix material has a modulus between about 10.sup.4 Pa and about 10.sup.8 Pa at 23.degree. C., and a glass transition temperature less than 0.degree. C. The matrix comprises polyurethane formed by reacting hydroxyl-terminated polybutadiene or polyisoprene and 4,4' diphenylmethane diisocyanate, and the insecticide is 2,2' dichlorovinyl dimethyl phosphate. The insecticide-containing matrix is contained in a plastic bottle, and typically protected against inadvertent skin contact by means of a dermal barrier. The article also comprises means for activating the article such that, prior to activation, release of insecticide into the ambient air is prevented, whereas such release can take place after activation. Exemplary activation means comprise a metal foil seal of the plastic bottle. The article is effective in controlling insect infestation (e.g.Type: GrantFiled: April 28, 1986Date of Patent: August 30, 1988Assignee: American Telephone and Telegraph Company, AT&T LaboratoriesInventors: John T.

Patent number: 4755547Abstract: Included are halogenated phosphate-phosphites and their acid halides and acids. The halogenated phosphate-phosphites can be prepared by a process comprising serially contacting(A) a phosphorus trihalide with a triol;(B) a halogenating agent; and(C) an oxirane or an alcohol,under conditions sufficient to prepare the halogenated phosphate-phosphite. Steps (A) and (B) can prepare their acid halides. Use of water in step (C) can prepare their acids. For example, 3-((bis(2-chloroethoxy)phosphino)oxy)(2-bromomethyl-2-methylpropyl, 2-bromoethyl, 2-chloroethyl)-phosphorate can be prepared from 2-methyl-2-(hydroxymethyl)-1,3-propanediol; phosphorus trichloride; bromine; and ethylene oxide.Also included is use of the compounds as a hydraulic fluid or flame retardant. For example, polyurethanes can be rendered less flammable with the halogenated phosphate-phosphite flame retardant.Type: GrantFiled: April 8, 1986Date of Patent: July 5, 1988Assignee: The Dow Chemical CompanyInventor: Chester E.
