摘要:
Described are processes for preparing brominated diphenylalkane products which are far whiter than prior known brominated diphenylalkane products. The resultant white brominated diphenylalkane products also form a part of the present invention, as do formulations incorporating the white brominated diphenylalkane products, and articles prepared therefrom.
摘要:
Novel polymer compositions of specified formula are converted into pellets of this invention by process technology provided by this invention. By forming a binder free melt of a polymer of such polymer compositions, and converting the melt into pellets as described here-in, pellets can be formed produce during production, handling, and use, no more than acceptably small amounts of “fines” or air-entrainable dusts.
摘要:
This invention relates to novel and useful toluene and styrene derived telomer distributions, such distributions being desirable substrates for the preparation of brominated flame retardants.
摘要:
The present invention relates to low triphenyl phosphate, high phosphorous content aryl phosphates with high ortho alkylation that are suitable for use as flame retardant compositions, processes for their preparation, and their use as flame retardants.
摘要:
Described is process technology for producing brominated aromatic polymer compositions from low molecular weight aromatic polymer compositions. The specified conditions used in the process enable the formation of products having superior color and thermal stability properties.
摘要:
This invention relates to a phosphorus flame retardant composition formed from bringing together components comprising: a) a cyclic phosphanate flame retardant comprising (5-ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl methyl ester of P-alkylphosphonic acid, and bis[(5-ethyl-2-methyI-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl]ester of P-alkylphosphonic acid; and b) an alkylated triaryl phosphate ester flame retardant having a triphenyl phosphate (TTP) content of less than about 1 wt % based on the total weight of the alkylated triaryl phosphate ester. This invention further relates to the use of this phosphorus flame retardant composition especially for in polyurethane foams and textile applications.

This invention relates to novel and useful toluene and styrene derived telomer distributions, such distributions being desirable substrates for the preparation of brominated flame retardants.
摘要:
New branched or star-branched styrene polymeric, telomeric, and monomeric product distributions, their preparation, their use as raw materials for bromination to produce flame retardants, the flame retardants themselves, and their use as flame retardants in various polymeric substrates are described.
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.
