Patent ID: 7674385

Claim:
A composition for reducing aluminosilicate scale in an industrial process comprising a polymer according to the formula: A-{CH 2 CHOHCH 2 O—(CH 2 CH 2 O) x (CH 2 CH(CH 3 )O) y (CH 2 CH 2 O) z —CH 2 CHOHCH 2 O—(B)} a — wherein, a=1-100, x/x+y+z=5-100%, y/x+y+z and z/x+y+z=0-100% and at least one A or B unit is O—Ar—Si(OR″) 3 or O—(CH 2 ) 1-10 —Si(OR″) 3 ; where Ar is an aralkyl or aromatic group; where R″ is selected from the group consisting of H, a C 1 -C 20 alkyl, alkenyl, aryl, or aralkyl group optionally substituted, a group I or II metal, and ammonium salts of formula NR1R2R3R4 + where R1, R2, R3, R4, are independently selected from H, a C1-C20 alkyl, alkenyl, aryl, or aralkyl group optionally substituted; and wherein said polymer comprises a reaction product of: (a) a polyalkylene oxide polymer chosen from: polyethylene oxide polymers, polypropylene oxide polymers, and polyethylene-polypropylene oxide copolymers; and (b) an organic compound containing glycidoxy functionality and a —Si(OR″) 3 functionality.
