Abstract
There is disclosed a porous moisture-absorbing and desorbing polymer, characterized in that, said polymer is an organic polymer containing 2.0-12.0 meq/g of carboxyl groups of a salt type, having a cross-linking structure and having macropores of not less than 1 m2/g of specific surface area and 0.005-1.0 μm of average pore size.
Claims8
A porous moisture-absorbing and desorbing polymer comprising a co-polymer containing not less than 50% by weight of an acrylonitrile monomer, said co-polymer containing 2.0-12.0 meq/g of carboxyl groups of a salt type, having a cross-linking structure, and having pores of not less than 1 m2/g of specific surface area and 0.005-1.0 μm of average pore size, wherein the polymer has a ten-minute moisture-absorbing rage of greater than 9% by weight and a saturated moisture absorbing rate of greater than 25% by weight.
A porous moisture-absorbing and desorbing co-polymer comprising a vinyl or vinylidene polymerizable organic acid monomer and a polyvinyl crosslinking monomer, said co-polymer containing 2.0-12.0 meq/g of carboxyl groups of a salt type, having a cross-linking structure and having pores of not less than 1 m2/g of specific surface area and 0.005-1.0 μm of average pore size, wherein the polymer has a ten-minute moisture-absorbing rate of greater than 9% by weight and a saturated moisture absorbing rate of greater than 25% by weight.
