Abstract
Disclosed are flame retardant compositions comprised of (a) brominated anionic styrenic polymer, and (b) at least one polybrominated alpha-omega diphenylalkane having a total of at least 6 bromine atoms directly bonded to the phenyl rings and in the range of 1 to 6 carbon atoms in the alkylene group disposed between the phenyl groups, and specified flame retarded polymer compositions with which have been blended (a) and (b) individually or in combination.
Claims13
A flame retardant composition comprising a polymer comprised of one or more polymerized monomers that had a polymerizable olefinic double bond in the molecule and with which polymer has been blended a flame retardant quantity of a flame retardant amount of (a) brominated anionic styrenic polymer, and (b) at least one polybrominated alpha-omega diphenylalkane having a total of at least 6 bromine atoms directly bonded to the phenyl rings and in the range of 1 to 6 carbon atoms in the alkylene group disposed between the phenyl groups, said alkylene group being a linear alkylene group and wherein the polymer is one or more acyclic olefinic hydrocarbon homopolymers or copolymers.
A flame retardant composition comprising a polymer comprised of one or more polymerized monomers that had a polymerizable olefinic double bond in the molecule and with which polymer has been blended a flame retardant quantity of a flame retardant amount of (a) brominated anionic styrenic polymer, and (b) at least one polybrominated alpha-omega diphenylalkane having a total of at least 6 bromine atoms directly bonded to the phenyl rings and in the range of 1 to 6 carbon atoms in the alkylene group disposed between the phenyl groups, said alkylene group being a linear alkylene group and wherein the polymer is one or more copolymers of at least one vinylaromatic monomer and at least one non-vinylaromatic monomer containing a functional group.
A flame retardant composition comprising syndiotactic polypropylene or a blend of syndiotactic polypropylene and isotactic polypropylene with which has been blended a flame retardant amount of (a) brominated anionic styrenic polymer, and (b) at least one polybrominated alpha-omega diphenylalkane having a total of at least 6 bromine atoms directly bonded to the phenyl rings and in the range of 1 to 6 carbon atoms in the alkylene group disposed between the phenyl groups, said alkylene group being a linear alkylene group.
