Halogen substituted phthalimide flame retardants

摘要

Novel halogen-substituted phthalimides are provided which are the reaction product of a halogenated phthalic anhydride with an alkoxylated amine or the reaction product of a halogenated phthalic anhydride with a siloxy amine. The halogen-substituted phthalimides are useful in increasing the flame retardancy of thermoplastic and thermosetting resins, and are also effective as processing aids in improving the flowability and moldability of thermoplastic resins during melt processing.
