The present invention refers to a flame retardant comprising a complex formed by phosphine oxide and transition metal salt, wherein has good flame retardant property. The present invention also refers to a composite flame retardant and flame retardant antistatic composition, wherein composite flame retardant comprise the flame retardant and the inorganic flame retardant component as described above, which has an enhanced flame retardant effect; said flame retardant antistatic composition, comprising above described flame retardant or composite flame retardant and carbon nanofiber antistatic agent, wherein carbon nanofiber antistatic agent could have interaction with flame retardant, effectively reducing the amount of flame retardant, and the combination with the flame retardant without the adverse effect of each other which result in negative performance of each other, does not influence the subsequent foaming process and the foam structure and physical properties. The present invention also further refers to a flame resistant method, which adds the abovementioned flame retardant, composite flame retardant or flame retardant antistatic composition into the material, so that said material has flame retardance or flame retardance and antistatic, and has excellent mechanical properties.

A bead foam is made of thermoplastic polyurethane, a styrene polymer, and an impact modifier. Moldings can be produced from the bead foam and processes for the production of the bead foams and moldings can be utilized. The moldings can be used for shoe intermediate soles, shoe insoles, shoe combisoles, cushioning elements for shoes, bicycle saddles, bicycle tires, damping elements, cushioning, mattresses, underlays, grips, protective films, in components in the automobile-interior sector or automobile-exterior sector, balls and sports equipment, or as floorcovering.

Disclosed are ionomers of co-polymers of vinylidene substituted aromatic monomers and unsaturated compounds containing acid groups crosslinked by the residue of one or more metal salts and/or metal oxides of a metal having a valence of 2 or greater. The crosslinks are reversible and the weight average molecular weight of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids may be substantially the same after the crosslinking is reversed as it is before crosslinking. A portion of the chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids are crosslinked with other chains of the copolymer of one or more vinylidene aromatic monomers and one or more unsaturated acids. Disclosed are methods of preparing such ionomers
