The invention relates to a material which comprises at least 20% of polyphenylene ether and which comprises as a flame-retardant 0.05-10% by weight of a boron compound, for example, boric acid, B.sub.2 O.sub.3, borate, salts or borate esters related to the polyphenylene ether, as well as optionally a plasticiser and further conventionally used additives.

Thermoplastic composition with boron compound

A composition comprising a copolyestercarbonate derived from a dihydric phenol, a carbonate precursor, and an aliphatic alpha omega dicarboxylic acid or ester precursor wherein the dicarboxylic acid or ester precursor has from 10 to about 20 carbon atoms, inclusive, and is present in the copolyestercarbonate in quantities of from about 2 to 30 mole percent of the dihydric phenol.

Copolyestercarbonate composition derived from dihydricphenol, carbonate

The invention relates to a material which comprises at least 20% of polyphenylene ether and which comprises as a flame-retardant 0.05-10% by weight of a boron compound, for example, boric acid, B.sub.2 O.sub.3, borate, salts or borate esters related to the polyphenylene ether, as well as, optionally, a plasticiser and further conventionally used additives.

Phenolic compound end capped polyester carbonate

The invention relates to polymer mixtures which comprise a polyphenylene ether, a sterically hindered amine, an epoxy compound, and a salt of a fatty acid. The polymer mixtures according to the invention have a good stability against discoloring by light.

Polymer mixture comprising polyphenylene ether, sterically hindered

A composition comprising an aromatic polycarbonate in admixture with a mold release effective amount of an ester of an aliphatic carboxylic acid of 6 to about 9 carbon atoms and a trihydric or tetrahydric alcohol.

Tri or tetraesters of aliphatic monocarboxylic acids of 6 to 9 carbon

The invention relates to a polymer mixture which comprises an aromatic polycarbonate, a styrene-containing copolymer and/or a styrene-containing graft polymer and a flame-retardant. It has been found that the use of a certain type of flame-retardants, namely oligomeric phosphates leads to a polymer mixture having improved properties. In particular to a polymer mixture having a good combination of flame retardancy, non-juicing characteristics of the flame retardant, good plastifying effect and good heat resistance.

Polymer mixture having aromatic polycarbonate, styrene I containing

Novel flame retardant polycarbonates are prepared that maintain a T.sub.g and an impact strength similar to that of non-modified polycarbonates. More particular, phosphine oxide containing polycarbonates are prepared that demonstrate improved flame retardancy and the retention of impact strength and glass transition temperature.

Phosphine oxide substituted polycarbonate

The flame-retardant properties of polymers with an aromatic main chain can be improved by incorporating therein a fluorine compound in combination with a boron compound.
