Abstract
The disclosure teaches a blend of a predominant amount of a polyphosphate flame retardant and an effective amount of a liquid crystalline additive for viscosity reduction and compatibilization when blended with a thermoplastic polymer, as compared to use of just the polyphosphate flame retardant alone. The polyphosphate can comprise resorcinol bis(diphenyl phosphate) and/or its higher oligomers. The liquid can be a liquid crystalline segmented block copolymer or a liquid crystalline oligomer.
