Brominated polystyrene Chemical Properties,Usage,Production

Description

Brominated polystyrene is a white or light yellow powder or granule. It is non-toxic and non-flammable and provides outstanding thermal stability and electrical performance. Brominated Polystyrene is used in engineering plastics such as polyester (PET, PBT, and PCT) and polyamides (nylons). 

Production method

A brominated polystyrene product made by the process comprising:pretreating a solution of a polystyrene reactant comprising from about five to about 20 percent by weight of said polystyrene reactant, in a halogenated hydrocarbon solvent with at least about 0.1 percent by weight of an additive to suppress halogenation of the polystyrene backbone, prior to brominating the polystyrene in the presence of a catalyst;subsequently adding a metal halide bromination catalyst to said solution, capable of effecting bromination of the ring without causing crosslinking of the polystyrene;adding to said solution from about 1 to about 3.4 moles of a brominating agent, per mole of polystyrene repeating units;reacting said polystyrene with said brominating agent at a temperature of from about −20° C. to about 50° C., and isolating the brominated polystyrene.

Uses

Brominated polystyrene is a kind of new-type bromine flame-retardant materials, it is formed with PS catalysis by the bromine and crushed to become white powder. Brominated polystyrene is a kind of new-type bromine flame-retardant materials, it is formed with PS catalysis by the bromine and crushed to become white powder. It is high flame-retardant, hot stability, and engineering plastics compatibility is good, , toxicity is low, It is particularly suitable for engineering plasticapplications such as polyesters (PET, PBT, PCT) and polyamides (nylons).It has outstanding thermal stability. It is an ideal choice for high temperature applications such as engineering plastics.

Uses

Bromopolystyrene is flame retardant provides outstanding thermal stability and electrical performance. It is particularly suitable for engineering plastic applications such as polyesters (PET, PBT, PC T) and polyamides (nylons).
