Improvements of the processability of an antistatic blend of PPE and polystyrene through the addition of a styrene acrylic acid copolymer

摘要

Antistatic thermoplastic molding compositions comprising (1) polyphenylene ether resin with or without a styrene resin, preferably with a high impact polystyrene resin, (2) an alkenyl aromatic resin copolymerized with an olefin acid and (3) one or more antistatic additives are described. The compositions are more stable against losses of the antistatic additive due to migration, volatilization, washing out and the like, due to the attraction of the anti­static agent to the olefin acid portion of component (2).
