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.
