Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C07F 911 C07F 914
US Classification:
260977
Abstract:
Novel (halo)(hydroxy)-substituted phosphorus-containing acid derivatives are disclosed. Preferred compounds are 2-halo-3-hydroxypropyl ester derivatives of phosphorous and phosphoric acid formed by reaction of at least some amount of tertiary butyl glycidyl ether with a halogenated derivative of a phosphorus-containing acid followed by acid dealkylation of the product. The polyol products are useful in the production of polyurethane articles such as foams having increased resistance to the effects of fire.

International Classification:
C07F 911 C07F 932 C08G 1800
US Classification:
260928
Abstract:
The invention is phosphorus compounds containing. alpha. -halo hydroxyalkyl or. alpha. -halo t-alkoxyalkyl groups corresponding to the formula ##STR1## wherein R independently in each occurrence is alkylene, haloalkylene, alkenylene, haloalkenylene, phenylene, diphenylene, halophenylene, dihalophenylene, and oxyalkylene; R. sup. 1 independently in each occurrence is hydrogen, CH. sub. 2 OR. sup. 3, CH. sub. 2 OH, haloalkyl, phenyl, halophenyl or methyl phenoxy; R. sup. 2 independently in each occurrence is haloalkyl, phenyl, haloaryl or alkyl; R. sup. 3 independently in each occurrence is t-alkyl; X independently in each occurrence is bromine or chlorine; a is independently in each occurrence 1 or 2; and b is independently in each occurrence 0 or 1, with the proviso that at least one R. sup. 1 is CH. sub. 2 OR. sup. 3 or CH. sub. 2 OH.

International Classification:
C07F 909
US Classification:
260929
Abstract:
Polyhydroxyl polyether compounds containing at least one monomeric unit each of the formulae: ##STR1## are disclosed. Polymeric condensation resins are prepared by allowing the polyhydroxyl polyethers to react with polyfunctional chain-forming compounds containing functional groups reactive with the hydroxyl groups of polyhydroxyl polyethers. The polyhydroxyl polyether compounds enhance the flame-retardant properties of polymeric condensation resins such as polyurethanes.

The stabilized complexes are useful as sanitizers.
Polyurethanes With Mono-Ol/Diol Haloneocarbyl Polyethers And Their Esters
Chester E. Pawloski - Bay City MI Sally P. Ginter - Sanford MI David J. Wampfler - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C08G 1800 C08G 1814
US Classification:
521171
Abstract:
Included are mondiol haloneocarbyl polyethers and their esters incorporated in polyurethane foams. The compositions have haloneocarbyl moieties, and in general, the polyethers before the incorporation in the polyurethanes contain from one to two hydroxy moieties. The polyurethane foam compositions are flame-retardant and can have little or no scorch and little or no odor.

Electroconductive Coatings Having Excellent Coating Holdout Properties
Sally P. Ginter - Midland MI Ralph E. Friedrich - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C08L 4700
US Classification:
260 296WB
Abstract:
An electroconductive composition useful for coating raw paper stock is provided by combining (1) an electroconductive resin, e. g. , poly(vinyl/benzyl trimethyl ammonium chloride) and (2) a water-swellable, cross-linked polymer, e. g. , crosslinked polyacrylamide, in the form of discrete particles having swollen diameters in the range from about 1 to about 100 micrometers. Application of this electroconductive coating composition to paper or to some other nonconductive substrate yields an article having decreased surface electrical resistivity and increased organic solvent resistance or holdout. Solvent resistance and other coating properties are further enhanced by including in the electroconductive composition a water-dispersible, film-forming amide polymer and a low viscosity binder such as a latex of styrene/butadiene copolymer.
