Title:
シラン変性カチオン化高分子化合物の製造方法
Document Type and Number:
Japanese Patent JP5577331
Kind Code:
B2
Abstract:
A process for producing a silane-modified cationized polymeric compound, the process including the steps of: (1) cationizing a water-soluble polymeric compound in a mixed solvent of a water-miscible organic solvent and water in the presence of an alkali to produce a slurry containing a cationized polymeric compound, (2) adding an aminosilane compound to the slurry or a cake produced therefrom, thereby treating the cationized polymeric compound with the aminosilane compound, (3) optionally adding an acid to the slurry obtained in step (1) or a product obtained in step (2), and (4) drying a product obtained in step (2) or a product obtained by performing step (3) after step (2), wherein the drying step (4) includes a primary drying treatment step of performing drying at a temperature of 50 to 140° C. under a degree of vacuum of 4.0 to 53.3 kPa, and a secondary drying treatment step of drying the product obtained following the primary drying treatment at a temperature of 90 to 155° C. The process enables a silane-modified cationized polymeric compound having excellent water dispersibility to be produced with good efficiency.
