HALOBENZOATE ESTERS, FLAME-RETARDANT COMPOSITION CONTAINING SAME AND, POLYURETHANE FOAM MADE THEREWITH

摘要

There is provided herein a hydroxyl group-terminated halobenzoate ester of the general formula (1), wherein each X independently is bromine, chlorine, or hydrogen, provided that at least one X is bromine or chlorine, and R is a divalent organic group of from 1 to about 20 carbon atoms, wherein R can optionally contain at least one additional hydroxyl group. There is also provided herein a flame-retardant composition, which comprises a first flame-retardant which is at least one of the aforementioned ester and further comprises a second flame-retardant which is at least one phosphate ester. There is provided flame-retardant polyurethane foams comprising said ester or said composition. There is still also provided herein, process(es) of making the hydroxyl group-terminated halobenzoate ester of the general formula (1) wherein R is a divalent organic group of from 2 to about 20 carbon atoms, wherein R can optionally contain at least one additional hydroxyl group, and polyurethane foams made using the same.
