Abstract:
As the initial step in a study of the role of polymer
melt viscosity in polymer burning behavior, a simpler,
non-burning configuration has been examined. Vertical
slabs of two types of polypropylene have been subjected
to uniform radiative heating on one face. The subsequent
melt flow process was monitored by measuring weights,
temperatures and flow velocities. A low MW polypropylene
flowed freely at temperatures below those for
significant degradation whereas a commercial
polypropylene of higher MW degraded and gasified
extensively. Plans are described for modeling the
non-reactive case first.
