PROCESS FOR PREPARATION OF WATER ABSORPTIVE COMPOSITE MATERIAL |
摘要 |
<p>There is provided a process for preparing a water absorptive composite material, which comprises the combination of the following steps of: (A) applying an aqueous solution of a polymerizable monomer comprising as a main component acrylic acid, of which 20% or more of the carboxyl groups have been neutralized to its alkali metal salt or ammonium salt, to a prefabricated fibrous substrate; (B) polymerizing the polymerizable monomers applied to said fibrous substrate to form a composite of a polymer derived from said polymerizable monomer and said fibrous substrate; and (C) irradiating ultraviolet rays onto said composite with its water content being 0.01 to 40 parts by weight per 1 part by weight of said polymer to obtain a water absorptive composite having a lower content of unpolymerized monomers than said composite. a</p> |
