摘要:
New highly-effective non-halogen, low VOC, low fogging, and cost-effective oligomeric polyphosphonate flame retardants for flexible polyurethane foams as well as for other flame retardant applications are described. In addition, methods for the preparation and uses of such new highly effective flame retardants are described. Formula (I)
摘要:
This invention provides a process for the preparation of a dihydrocarbyl hydrocarbonphosphonate. The process comprises forming a reaction mixture from components comprising (i) at least one dihydrocarbyl phosphite, (ii) at least one alkali metal hydrocarbyloxide, and (iii) at least one alcohol, so that a dihydrocarbyl hydrocarbonphosphonate is formed.

摘要:
This invention provides chlorohydrocarbyloxy phosphonate oligomers, organophosphonate oligomers, and processes for the preparation of such oligomers. The chlorohydrocarbyloxy phosphonate oligomers can be represented by the formula (IV) where R1 is a linear or branched hydrocarbylene group or oxygen-containing hydrocarbylene group, which hydrocarbylene group has about two to about twenty carbon atoms, or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; R2 is an alkyl group or an aromatic group; and n is a number from about 2 to about 20.
