Novel (halo)(hydroxy)-substituted phosphorus-containing acid derivatives are disclosed. Preferred compounds are 2-halo-3-hydroxypropyl ester derivatives of phosphorus 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. The derivatives can be additives or reactants in the polyurethane, depending on the presence or absence of terminal hydroxyl groups within the given ester moieties.

(Halo)(hydroxy)-substituted phosphites and phosphorates

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.

Polyurethanes with mono-ol/diol haloneocarbyl polyethers and their esters

The invention is phosphono-s-triazines corresponding to the formula ##STR1## wherein: X is separately in each occurrence chlorine, bromine, haloalkyl or alkyl;

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;

Halogenated phosphorus hydroxy-alkyl and t-alkoxyalkyl esters

Primary hydroxyl-containing phosphono-s-triazines

Adhesion of polylefin resins to various substrates is enhanced by the incorporation of a poly-2-oxazoline, e.g., poly(2-ethyl-2-oxazoline) into the polyolefin.

Polyolefin resin blends with enhanced adhesion and laminates

Novel flame retardant compositions, which are useful in the preparation of rigid polyurethane foams, comprise a sucrose polyol, an aromatic polyester polyol, and a brominated, hydroxyl-containing pentaerythritol.

Flame retardant for use in rigid polyurethane foams

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.

Process for preparation of (halo)(hydroxy)-substituted phosphites and

The title complexes comprise (a) a poly-2-oxazoline or poly-2-oxazine, such as the homopolymers of polymerized 2-ethyl-2-oxazoline or 2-ethyl-2-oxazine, and (b) IBrCl.sup.- or polyhalide anion of the formula (XY.sub.2n).sup.- where X and Y are individually chloride, bromide or iodide, but not both chloride, and n is 1, 2 or 3, and an independently supplied cation selected from the group consisting of alkali metals, alkaline earth metals, hydrogen and mixtures thereof. These complexes are readily prepared in either an aqueous or anhydrous environment at room temperature and are significantly more stable than either complexes of polyoxazolines or polyoxazines and halogen or interhalogen; or complexes of polyvinylpyrrolidone and polyhalide anions.

Sanitizing complexes of polyoxazolines or polyoxazines and polyhalide

Adhesion of polyolefin resins to various substrates is enhanced by the incorporation of a poly-2-oxazoline, e.g., poly(2-ethyl-2-oxazoline) into the polyolefin.

Polyolefin resin blends with enhanced adhesion

Phosphorus-containing polyether polyols are prepared by reacting phosphorus-containing acids with tertiary alkyl glycidyl ether and subsequently dealkylating the tertiary alkyl functionality.
