The Solid Phase Polymerisation (SPP) technique is
widely applied in industrial manufacture of
certain polymers to achieve improved processing
and/or finished product features. Finished
products can include food/drink containers, wide
temperature range usage speciality films and
superior industrial fibres, monofilaments and
sheet. Solid Phase Polymerisation (SPP) is a
chemical process in which the polymer chain
length is increased by the controlled application
of heat in the absence of oxygen and water by
means of either a vacuum or by purging, with an
inert gas, to drive off the by-products of the
reaction. The reactivity is a function of polymer
type, applied temperature and pressure and the
diffusion of the by-products from the pellet
centre to the outer surface. SPP is an important
step frequently employed after melt
polymerisation for the purpose of improving the
mechanical and rheological properties of the
polymers. The batch process and systems employed
by PETUK enables extremely high accuracy of the
product measured molecular weight (IV) and
repeatability between batches.
