摘要：

Brominated phosphate, brominated polycarbonate oligomer, and brominated polystyrene were compared as flame retardants for glass-filled polybutylene terephthalate resin. Properties compared are flammability, impact resistance, heat distortion temperature, tensile and flexural properties and processability. Also studied in detail are polymer compounding character istics and rheological properties. The brominated phosphate flame retardant was shown to give the best balance of properties for glass-filled polybutylene terephthalate. The viscosity and shear sensitivity data indicate that the PBT/brominated phosphate resin should have the best mold flow. Normalized output data show the extrusion process to be Zone 3 controlled. Mechanical energy data indicate this resin would require the least energy at high shear rates. These studies conclude that the PBT/brominated phosphate resin has superior processing characteristics. © 1990, Sage Publications. All rights reserved.
