通过使用微秒和毫秒持续时间的紫外激光脉冲，它示出了由紫外激光辐射的Kapton变换的化学强烈地依赖于激光束的强度（功率/单位面积）。在这些长脉冲下，聚合物没有被烧蚀。分解导致聚合物重量的51%转化为主要由CO（67%）、HCN（15%）、C2 H2（12%）和一些（
By the use of ultraviolet laser pulses of microsecond and millisecond duration it is shown that the chemistry of the transformations of Kapton by UV laser radiation is strongly dependent on the intensity (power/unit area) of the laser beam. With these long pulses, the polymer was not ablated. The decomposition resulted in 51% of the polymer weight being converted to gaseous products consisting mostly of CO (67%), HCN (15%), C2H2 (12%), and some (
