Flame retardant PBT / TPE blends with inherent antistatic properties

摘要

The invention relates to a polymer mixture which comprises A) a polyester and B) a copolyether ester block copolymer having a polyether block derived from an ethylene oxide-capped poly(propylene oxide)glycol, having an ethylene oxide content of 15-35 % by weight and a number-averaged molecular weight of 1,500-3,000. Articles formed from the polymer mixture according to the invention have a reduced surface resistance. Addition of a flame-retardant leads to a further reduction of the surface resistance.
