| titleOfInvention | Process for efficient utilization of chain transfer agent |
| abstract | A process for using hypophosphorous acid or its salts as a chain transfer agent comprises polymerising one or more monomers, where at least 20 wt. % of the monomers are monoethylenically unsaturated acids or their salts, in the presence of: (a) water; (b) one or more water-soluble initiators; and (c) hypophosphorous acid or its salt; where 80-100 % of the monoethylenically unsaturated acids or their salts are metered into a polymerisation reactor contg. water, and 0-100% of the hypophosphorous acid or its salt, to provide a final polymer solids level of at least 50 wt.%. |
