Patent ID: 8476373

Claim:
A brominated flame retardant composition which comprises a brominated aromatic substrate distribution formed from a polymethylated benzene having 2 to 4 methyl groups in the molecule, and styrene, said brominated aromatic substrate distribution having the formula: (CH 3 ) b C 6 H x Br y (CH 2 (CH 2 CHC 6 H i Br j ) n CH 2 CH 2 C 6 H i Br j ) c (VI) wherein each C 6 H i Br j is a brominated phenyl group and each C 6 H x Br y is a brominated substituted phenyl group and for each molecule of said formula, n is a whole number and is independently in the range of 0≦n≦8; b is, independently, a whole number in the range of 0 to 3; c is, independently, a whole number in the range of 1 to 4 and wherein when b=0, c is in the range of 2 to 4; x is, independently, a whole number in the range of 0 to 3; y is, independently, a whole number in the range 1 to 4; i is, independently, a whole number in the range 0 to 4; j is, independently, a whole number in the range of 1 to 5; and the sum of x+y+b+c=6 and the sum of i+j=5 for any discrete C 6 H i Br j brominated phenyl group, and wherein said distribution is further characterized by having an M n in the range of about 420 to about 3300, an M w in the range of about 420 to about 6250, an M z in the range of about 420 to about 10937, and a PD in the range of about 1.00 to about 2.00, and wherein the weight percent of bromine as determined by XRF in the brominated product distribution is in the range of about 45 wt % to about 79 wt %.
