Pyrolytic conversion of poly(4-((trimethylstannyl)methyl)styrene) (1) film
to SnO2 was studied. The pyrolysis at 500 degrees C of the polymer film whi
ch was crosslinked by 248 nm light or electron beam irradiation afforded a
SnO2 film. The crosslinking network formation is necessary for the conversi
on of 1 into SnO2 through the encapsulation of the low molecular weight int
ermediates to prevent their escape from the polymer film.
