摘要

"Pope poliacru00eclico granular acid processes, to provide for controlled release applications poliacru00eclico acid and to produce a controlled release tablet, and,The product of acid poliacru00eclico ".The present invention relates to a process for the formation of granules of polyacrylic acid and granules formed in the granules are fluu00edveis,Have an apparent density increased on poliacru00edlicos acids polymerised.And a low amount of residue which is in general characterized here as particles which pass through a sieve grid 325.The granules are formed by the process of this invention can be used to prepare tablets, controlled release tablets, in particular pharmaceutical controlled release.The properties of controlled release tablets of the formed granules prepared in accordance with the present invention are unexpectedly better than tablets prepared from granules formedS other granulation processes are known.
