摘要

日常生活中常見的塑膠材質用品在自然環境下，會因為太陽光中的紫外線照射下導致黃化、老化與脆化現象產生，為提高塑膠高分子聚合體穩定性，得以延長塑膠材質用品的使用時間，添加安定劑去阻止暴露在空氣下紫外光所造成的衰變是常見的方式。因此發展新結構具複和型的紫外線吸收安定劑可有效將造成高分子塑膠材料衰變的高能量紫外線加以吸收，並可進一步防止塑膠材料中因自由基所產生的連鎖裂解反應。
實驗研究目的是將一次抗氧化劑和Benzotriazole紫外線吸收劑加以結合為單一結構，不但使單一結構擁有紫外線吸收功能，並具有抗氧化功能。在工業加工上可減少必需同時添加紫外線吸收劑及抗氧化劑的困擾。最後探討多功能型紫外線劑與一般常見紫外線吸收劑應用在不同塑膠材質上所帶來的防氧化、裂化和黃變功效差異。

The daily life of common plastic materials supplies in the natural environment because of the sun's ultraviolet radiation in the cause yellowing, aging embrittlement phenomenon and that in order to enhance the stability of polymer plastic, to extend the use of plastic material supplies time, add stabilizer to prevent exposure to the air of decay caused by ultraviolet light is a common approach. Therefore the development of new structures and a complex type of UV absorption to be effective stabilizer polymer plastic material will result in decay of high-energy ultraviolet light to be absorbed, and further to prevent the plastic material due to free radicals generated by the chain cleavage reaction.
The purpose of the experiment is to study an anti-oxidant and Benzotriazole UV absorber to be combined into a single structure, not only has a single structure of the UV absorption, and has anti-oxidation function. In the industrial processes at the same time can reduce the need to add UV absorbers and antioxidants problems. Finally, to explore multi-agent-based ultraviolet absorbers and ultraviolet application of common plastic materials in different brought Oxide, cracking and yellowing differences in efficacy.
