Tribromoneopentyl phosphorus reactive flame retardants

Abstract

Compounds of the formula: [(BrCH.sub.2).sub.3 CCH.sub.2 O].sub.2 P(O)R wherein R is a functional group selected from the group consisting of --CH.dbd.CH.sub.2,--CH.sub.2 X, --OR'OC(O)CH.dbd.CH.sub.2, --OR'OC(O)C(CH.sub.3).dbd.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.
