Bromostyrene‐crosslinked polyesters. II. Mechanical properties and weathering stability

The partial replacement of styrene by bromostyrene in polyesters, in order to achieve fire‐retardant resins, raised the need to explore the effect of the bromine on the mechanical performance of these resins and of their glass fiber composites. The present study reveals that under combined humidity and uv radiation conditions, the mechanical performance of the bromine‐containing resin surpasses that of the original resin.
