Distribution and state analysis of light stabilizer in polypropylene by MALDI-MS imaging
MALDI-MS imaging was applied to the analysis of stabilizers in polymer samples. By using a model sample, it was proved that the combination of spraying and vapor deposition was the most effective procedure for the coating of matrix (DHB). Then the distribution and state of a hindered amine light stabilizer in polypropylene film samples were successfully visualized by MALDI-MS imaging
