Abstract: Liquid poly(haloethyl-ethyleneoxy) phosphoric acid esters are prepared by condensing tris (2-haloethyl) phosphate at a temperature of from 140.degree. to 220.degree. C. in the presence of a catalyst until from about 0.5 to about 0.9 moles of ethylene dihalide per mole of tris(2-haloethyl) phosphate is evolved. A low acidity product is obtained. Any residual acidity in the product is substantially eliminated by neutralization with an alkylene oxide.

Abstract: This invention relates to insecticidal active compositions. More specifically, this invention relates to the use of O,O'-dipropargyl chloromethylphosphonate as a synergist for a commercially available insecticidal active compound defined as O,O-dimethyl-O-(2-methoxy-4-cyanophenyl)-phosphorothioate.

Abstract: A method for inhibiting the growth of bacteria and fungi by exposing same to an effective amount of a salt of nitrilotriacetic acid with a higher aliphatic amine containing from about 8 to about 60 carbon atoms. The nitrilotriacetic acid is reacted with an amine containing alkyl, alkenyl and/or cycloalkyl radicals to provide the desired salt.

Abstract: Compounds having excellant insecticidal properties and utility as fire retardants have the formula: ##EQU1## wherein X is halogen, the R substituents can be hydrogen, hydrocarbon or substituted hydrocarbon radicals, and the R.sub.7 and R.sub.8 can additionally be halogen. Halogenation products of the foregoing compounds are especially useful.

Abstract: A process is disclosed for forming polymers and oligomers containing the repeating unit ##EQU1## where R is selected from the group consisting of hydrogen and hydrocarbyl, preferably C.sub.1 -C.sub.4 alkyl groups, e.g., methyl and ethyl, and R' is an alkylene group, e.g., a C.sub.2 -C.sub.4 alkylene group, a substituted alkylene group, or an alkylene group having one or more O, S, arylene or vinylene group interruptions in its aliphatic chain. It comprises the transalkylation of a dihalide compound of the formula:X -- R' -- X,where R' has the same meaning given above and X is either chlorine or bromine and is attached to the terminal carbon atoms in R', with a phosphonate compound of the formula, RPO(OR").sub.2, where R is hydrogen or a hydrocarbyl group and R" is an alkyl group, by means of reaction of that dihalide with the phosphonate at an elevated temperature, e.g., about 120.degree.C-250.degree.C.

Abstract: Compounds of the formula:[(BrCH.sub.2).sub.3 CCH.sub.2 O].sub.2 P(O)Rwherein R is a functional group selected from the group consisting of --CH=CH.sub.2, --CH.sub.2 X, --OR'OC(O)CH=CH.sub.2, --OR'OC(O)C(CH.sub.3)=CH.sub.2, --O(R'O).sub.n H, --OH, --Cl, and NR"R'", wherein R' is a C.sub.1 -C.sub.4 alkylene group, wherein R" and R'" are the same or different and are selected from the group consisting of hydrogen, lower alkyl, e.g. C.sub.1 -C.sub.8, preferably C.sub.1 -C.sub.4, phenyl, hydroxyalkyl, e.g., hydroxy C.sub.1 -C.sub.8, or, preferably hydroxy C.sub.1 -C.sub.4, and allyl groups, wherein X is selected from the group consisting of chlorine and bromine and wherein n is an integer between 1 and 20 are disclosed. These compounds have flame retardancy characteristics and are useful either as flame retardant additives or as reactive flame retardants which can react to confer durable flame retardancy on textiles or other polymer products.
