Abstract
A method for forming polyacrylic acid granules and granules prepared therefrom, wherein the granules are flowable, have comparable swelling characteristics and provide comparable tablet properties to powdered polyacrylic acid, have increased bulk density and contain minimal amounts of very small particles that can cause dusting and static adherence. The granules are used to prepare controlled-release tablets, especially for pharmaceutical purposes. The tablets prepared from granules obtained by the method of present invention have superior controlled release properties.
