Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
110 words
A plastic composition consisting essentially of polyurethane having incorporated therein an effective amount of a flame retardant which is a compound having the formula: ##SPC5## wherein Z is selected from the group consisting of bromine or chlorine; m and m' are integers having a value of 1-5; i and i' are integers having a value of 0-2; HBCA is a halo-branched chain alkylene group having from 1 to 6 carbon atoms; and A is selected from the group consisting of cyano, nitro, lower alkoxy, lower alkyl, fluorine, dialkylamino, phenyl, halo-phenyl, benzyl and halo- benzyl, with the proviso that neither m + i nor m' + i' is greater than 5.
Claim 2
Dependent Claim
110 words
