Abstract

In this study, the accelerated degradation tests were conducted on PC/ABS blend (50:50) under various combinations of temperature and humidity, 85 °C-85 %RH, 85 °C-45 %RH, 75 °C-65 %RH, 85 °C-dry, 95 °C-dry, and 105 °C-dry conditions. The generation of surface damages were observed in detail, and a quantitative degree of degradation was defined based on the spectroscopic analysis. Also, the master curves correlating the degree of degradation with mechanical properties were constructed. The prediction model for degradation degree and mechanical properties under arbitrary temperature and humidity condition was suggested based on the degradation kinetics, and it was utilized to estimate the degradation behavior of field-weathered samples for 6 months. Based on this study, it is believed that the degradation behavior of PC/ABS blend under a wide range of weathering conditions can be predicted accurately by suggested protocol, and the reliable application potential of PC/ABS blends for various industrial areas is enhanced.

PC/ABS共混物在不同温度和湿度条件下的风化降解特性及建模

在本研究中，对PC/ABS共混物（50:50）在不同的温度和湿度组合，85°c - 85% RH、85°c - 45% RH、75°c - 65% RH、85°c -干燥、95°c -干燥和105°c -干燥条件下进行加速降解试验。详细观察了表面损伤的产生，并根据光谱分析确定了降解的定量程度。并建立了退化程度与力学性能的主曲线。提出了基于降解动力学的任意温湿度条件下的降解程度和力学性能预测模型，并利用该模型对野外风化样品6个月的降解行为进行了估计。研究结果表明，该方案可准确预测PC/ABS共混物在多种风化条件下的降解行为，增强了PC/ABS共混物在各种工业领域的可靠应用潜力。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
