| titleOfInvention | High-molecular porous body |
| abstract | PURPOSE: To provide the titled porous body having open cells, high porosity, and excellent water absorption, water retention, chemical resistance and mechanical strength, by reacting an aldehyde and an acid with a particular block copolymer having a PVA polymer as one component. n CONSTITUTION: A water-soluble or -dispersible block copolymer (A) contg. a PVA polymer with a vinyl alcohol unit of 20mol% or more and a degree of polymn. of 10 or above (a) and other component polymer such as a water-soluble or -swellable polymer [e.g., a water-soluble polymer with a monomer unit of (meth)acrylic acid (metal salt) and the like] or a polymer with a m.p. lower than ordinary temp. (e.g., a polymer contg. a monomer unit such as C 2 H 4 or C 3 H 6 ) (b) in a wt. ratio of 0.1≤a/b≤50, 80W300 mol%, based on the PVA polymer moiety of the component A, aldehyde such as HCHO (B), and 50W200mol%, based on the component C, acid such as sulfuric acid (C) are heated at 30W80°C for 5W50hr in the presence of a pore forming aid such as starch for acetal formation, and the reaction product is washed with (hot) water. n COPYRIGHT: (C)1986,JPO&Japio |
