Process for preparing and handling water-soluble-polymer gels |
| abstract |
A process for preparing high molecular weight water-soluble polymer gels having relatively narrow molecular weight distributions is disclosed. An aqueous reaction mixture comprising a solution of a water-soluble vinyl monomer and a suitable catalyst system is polymerized in a reactor comprising a channel reactor with sealed removable lid in the substantial absence of oxygen. The sealed removable lid is preferably flexible and sealed with a flexible zipper. The polymer gels are particulated to particles or pellets and coated. The coating allows the gel to flow or be pumped and metered. |
