  • Flame retardant resin composition containing styrenic polymers
    Patent number: 5194482
    Abstract: A flame retardant styrene composition that has improved impact strength is provided while maintaining heat deflection temperature and flexural modulus. The impact strength is improved through the use of a styrene butadiene block copolymer compatibilizing agent. In a preferred embodiment, the use of a brominated diphenyl oxide as a flame retardant is avoided.
