ABSTRACT:
In a papermaking process, improved drainage and retention are obtained when ionic, organic microbeads of less than about 1,000 nm in diameter if crosslinked or less about than 60 nm in diameter if noncrosslinked are added either alone or in combination with a high molecular weight organic polymer, and/or polysaccharide. Further addition of alum enhances drainage formation and retention properties in papermaking stock with and without the present of other additives used in papermaking processes.
