ANTI-CORROSIVE PHOSPHINATE FLAME RETARDANT COMPOSITIONS

摘要

The present invention relates to flame retardant polymer compositions which comprise phosphinic acid salts in combination with polymer chain extension agents on the basis of epoxide structures and oxides or hydroxides of selected metals. The compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, such as polybutylene terephthalate (PBT).
