Abstract
Disclosed are self-extinguishing polystyrenic compositions with improved thermal stability properties, comprising a styrenic resin and a fire-retardant agent which can either comprise solely a brominated pentaerythritol having at least one free-OH group or such a compound in combination with a peroxide.
Claims7
A self-extinguishing polystyrenic composition with improved thermal stability properties comprising a styrenic resin selected from the group consisting of crystalline polystyrene, rubber-reinforced polystyrene, acrylonitrile-butadiene-styrene resins, and polystyrene foams having blended therewith a fire retardant agent consisting essentially of dibromoneopentylglycol;
- the amount of dibromoneopentylglycol constituting less than 8 percent by weight of said composition.
