Introduction
• Superaborbent polymer 'SAP( are material that ha)e the ability to aborb and
retain lar$e )olume o# %ater and a*ueou olution there#ore earnin$ the term
uper aborbent.
• Thi make them ideal #or ue in %ater aborbin$ application uch a baby
nappie and adult incontinence pad to aborbent medical drein$ and controlled
releae medium.
•+arly uper aborbent %ere made #rom chemically modi#ied tarch and celluloe
and other polymer like poly')inyl alcohol( P,A- poly'ethylene oide( P+/ all o#
%hich are hydrophilic and ha)e a hi$h a##inity #or %ater.
• Today0 uperaborbent polymer are made #rom partially neutralied- li$htly
cro1linked poly'acrylic acid(- poly'acrylo nitrile(- %hich ha been pro)en to $i)e
the bet per#ormance )eru cot ratio.
•In %ater they %ell to a rubbery $el that in ome cae can be up to 22%t3 %ater.
