Halogenated phosphate polyesters
TLDR
HALOGENATED PHOSPHATE POLYESTERS, useful as FLAME RETARDANTS for POLYURETHANE FOAM, are described in this paper.Abstract:
HALOGENATED PHOSPHATE POLYESTERS, USEFUL AS FLAME RETARDANTS FOR POLYURETHANE FOAM, ARE DISCLOSED WHICH HAVE THE FORMULA R-(X)A-(O-P(=O)(-O-R'')2)N WHEREIN R IS AN ALIPHATIC HYDROCARBON RADICAL OF 1-8 CARBONS OR AN AROMATIC HYDROCARBON RADICAL, X IS A HALOGEN, A IS AN INTEGER OF 0-4 N IS AN INTEGER OF 2-6, AND EACH R'' IS INDEPENDENTLY A HALOALKYL RADICAL. ACCORDING TO PREFERRED EMBODIMENTS OF THE INVENTION, THESE POLYESTERS ARE REPRESENTED BY THE FORMULA (R''-O-)2-P(=O)-O-R-O-P(=O)(-O-R'')2 WHEREIN R AND R'' ARE AS INDICATED ABOVE.read more
