Abstract
Flame resistant, reinforced thermoplastic molding compositions based on polyethylene terephthalate resins were found to have a lowered tendency to drip during burning upon the addition thereto of a sufficient amount of a particular ionic elastomer. The addition of the drip suppressant in accordance with the invention does not compromise the physical and mechanical properties of the composition.
