- I have been experimenting with determining the integrity of cross linked
- polymers. So far I have exposing my samples in an oxygen rich plasma etch
- for 10 minutes then analyzing the sample in a SEM. I think we are seeing
- that examples of proper or "good" cross linked polymers show a grain of
- structure of uniform size and orientation while the "bad" samples seem
- to display a wide variation of grain size over a given area. Is this a
- viable method of analyzing such materials? Can anyone add anything to
- this? I am not very familiar with such materials so consider me mostly
- ignorant on this subject. Any information (in simple terms) would be of
- great help.

- Thanks,
