polymers have been reviewed in the literature [8].
The CVD method can be very useful for the prepa-
ration of a wide variety of insoluble PPV in desired
dimensions and shapes. The advent of the technique
used in this particular field arose in 1994 [9,10]. At
the moment, poly(p-xylylene)s are the only polymers
that are commercially fabricated by CVD. PPV can
be also obtained by CVD techniques using 1,4-bis-
(dichloromethyl)-benzene, α,α-dibromo-p-xylene, or
chlorinated cyclophanes.
1,9-Dichloro[2.2]paracyclophane can be deposited
via an intermediate ...
