IMPROVED BROMINATED POLYSTYRENIC RESINS

摘要

Novel brominated styrenic polymers having superior properties rendering them ideally suited for current commercial requirements for use as flame retardan ts in thermoplastic polymers are described. These properties include such high thermal stabilities in a standard Thermal Stability Test as to dramatically reduce if not eliminate the possibility of corrosion problems due to release of hydrogen halide at elevated polymer processing temperatures. Other specia l properties of the novel brominated styrenic polymers include, for example, l ow color or staining properties, and excellent melt flow characteristics.
