GRAFT POLYMER WITH HYDROCARBON GROUP AND METHOD FOR PRODUCING THE SAME

摘要

Provided is a polymer-based detergent builder which is capable of effectively suppressing deposition of a surfactant, and effectively preventing soil re-deposition, even in washing using high hardness water. Specifically, the present invention solves the above problem by a graft polymer with a hydrocarbon group made by graft polymerization of monomer components containing a hydrophilic monomer having an anionic group or a hydroxyl group, on a polyoxyalkylene-based compound represented by the following formula (1): wherein R represents a straight chain or branched C10 to C20 alkyl or alkenyl group; X represents: p represents 0 or 1; Y represents: wherein R1 to R4 represent a C2 to C6 alkylene group; R5 represents a hydrogen atom, or a group represented by the following formula (2): wherein R6 and R7 represent a C2 to C20 alkylene group; s represents an integer of 0 to 200; Z represents a C2 to C20 oxyalkylene group; q represents an integer of 17 to 200; and r represents an integer of 1 to 6.
