Anti-ultraviolet and weather-resistant polycarbonate (PC), focusing on the influence of factors such as the compound ratio and addition amount of benzotriazole ultraviolet absorbers on the weathering performance of PC. The results show that the compound ultraviolet absorber has a synergistic effect. Compared with a single ultraviolet absorber, the added amount of the compound ultraviolet absorber can be reduced by 0.05% to 0.1%.

The compound UV absorber has excellent thermal stability, and when the compound ratio is 40:60, the overall performance of PC is the best
