Claim 0:
1. A method of inhibiting silica scale formation, said method comprising the steps of: treating an aqueous system comprising silica with an effective amount of polymer comprising monomer A, monomer B, and monomer C, such that said polymer has the chemical formula:, wherein x=approximately 5 wt. %-approximately 45 wt. %; wherein y=approximately 55 wt. %-approximately 95 wt. %; wherein z=approximately 0 wt. %-approximately 25 wt. %;
wherein A is the repeat unit obtained after the polymerization of acrylic acid
wherein B is the repeat unit obtained after the polymerization of ethylene glycol methyl ether methacrylate
wherein C is the repeat unit obtained after the polymerization of one or more nonionic monomers selected from the group consisting of methacrylates, acrylates, and acrylamides.
