The trend towards miniaturization in microstructure fabrication has created a demand for improved methods of production. The preceding paper (l) detailed one of the areas of research in this area, development of a deep UV-degradable photo-resist and presented a likely candidate, poly(methyl methacrylate-co-3-oximino-2-butanone methacrylate-co-methacrylonitrile) (P(M-OM-CN)). 

It should not be thought, however, that perfluorocarbons are completely inert toward combustion. Even the very inert perfluorocarbon polymer polytetrafluoroethylene [PTFE, Du Pont s Teflon F(CF2CF2)nF] is thermodynamically unstable in oxygen with respect to CO2 and CF4 (Exercise 12.6) and can burn in a 95% 02/5% N2 mixture at 0.1 MPa, although combustion is hard to initiate because of the nonvolatility of PTFE and the resistance of the thermal degradation products to oxidation. Conflagrations involving more reactive, volatile fluorocarbons such as perfluoro-toluene have been reported.15... 

The radiation resistance of TBP-aliphatic compound solutions could be improved by the introduction of aromatic derivatives the addition of only 10% of aromatic diluents or 0.1 mol L 1 mono-fvo-propyldiphcnyl reduced the global concentration of the degradation products by half (91, 94).
