水性ポリマー分散液の調製方法、そのポリマー分散液、その使用ならびにその固体薬剤投与形
Document Type and Number:
Japanese Patent JP4629821
Kind Code:
B2
Abstract:
Preparation of an aqueous polymer dispersion comprises polymerization of at least one radical-polymerizable, ethylenically unsaturated monomer in an aqueous system in the presence of a polymerization initiator where the pH of the aqueous system is set by addition of at least two different basic reagents and where at least one of the basic reagents is added more than once. Independent claims are included for: (1) aqueous polymer dispersions obtained using the process; (2) polymer powders obtained by drying the aqueous dispersions; (3) use of the dispersions as auxiliaries or coating materials for solid pharmaceutical dosage forms; and (4) solid pharmaceutical dosage forms containing polymers prepared using the process.
