摘要

Ethylene-propylene (C2-C3) based polymers represent the largest class of synthetic polymers. They are used in numerous and varied applications in which the surface chemistry often plays a critical role Despite the importance of these surfaces, there has been no good way of quantitatively determining the comonomer concentration and sequence distribution on these surfaces (top 10-20A). Valence band XPS and static secondary ion mass spectrometry (SSIMS) analyses have been frequently used to distinguish polyethylene (PE), polypropylene (PP) and various types of EP, but have not provided quantitative information. In this report, new static time-of-flight secondary ion mass spectrometry (ToF-SIMS) techniques are presented for the quantitative surface characterization1 of C2-C3 polymers, These quantitative ToF-SIMS (jpabilities are then extended down to microscopic areas (a few microns in diameter) using the imaging capability of the instrument.
