Potential sources of the induced conversion wave operative during the polym
erization in the absence of heat and mass transfer are considered. It is sh
own that a stationary temperature field gives rise to the conversion wave.
However, only a quasifrontal regime of polymerization is realized for the u
sual observation times, whereby the width a of the conversion profile is co
mparable with (or less than) the characteristic size L of the system. A qua
sifrontal regime is also established in the case of a monotonic distributio
n of concentration of the initial monomer or an initiator (or a reagent in
the polymer matrix). In contrast to these mechanisms, a monotonic dependenc
e of the initial inhibitor concentration on the spatial coordinate may give
rise to the conversion wave having a narrow profile width a much less than
L. In all cases; the conversion label (corresponding to a narrow conversio
n interval observed) propagates iol the system like a traveling wave. Exper
imental data for the photopolymerization of butylglycidyl ester show that t
he induced conversion wave propagation may be determined by the geometry an
d characteristics of equipment used in the process.
