摘要
Abstract
The accelerated ageing experiment of Perspex (PMMA) YB-DM-11 were done for nearly two months in both 254nm and 313nm wave length ultraviolet. Tensile stress and mass were measured during the experiment. Thus the changing rules of both parameters were obtained. The samples structure difference were founded between before ageing and after ageing by methods of IR, TG/DTA,GPC and SEM. Analyzed results above all, the ageing mechanisms of PMMA in ultraviolet were clarified qualitatively.关键词
