Abstract
Flame retardant polymer compositions with excellent processing stability and flame retardant activity are obtained by incorporating into the polymer a flame retardant obtained by heating certain phosphonic acid salts at temperatures of 200° C. or higher and as flame retardant synergist melam or a melam derivative, which compositions are more readily processed under certain harsh conditions than similar compositions comprising similar synergists such as melem, melon and the like.
