Macro photoinitiators possessing polyethylene glycol(PEG) segments were used for radical polymerization of acrylamide(AAm) to yield high molecular weight block copolymers (PAAm-b-PEG-b-PAAm) composed of PEG and polyacrylamide(PAAm) as the inner segment and outer segment respectively. The block copolymers were used as flocculates to clear a saturated borax solution prepared from tincal concentrate and showed good flocculating properties.
