Abstract

The study develops an oxidative kinetic model of acrylic-urethane network during photo-aging. The kinetic model can track chemical reaction dynamics well and also enables to estimate the network lifetime by counting scission/crosslinking events. Estimated network lifetime is semiquantitively coincided with the one derived from different statistical approach.

通过动力学模型和 "退化 "模型估算光老化过程中 AUN 的网络寿命

该研究建立了丙烯酸-聚氨酯网络在光老化过程中的氧化动力学模型。该动力学模型能很好地跟踪化学反应动力学，还能通过计算裂解/交联事件来估算网络寿命。估算出的网络寿命与不同统计方法得出的网络寿命基本吻合。
