Embodiment 1

[0193] Add 99.0 g of monomer 1 into a 500 mL capacity detachable glass flask equipped with a stirring device (stirring wing), then raise the temperature to 120° C. under stirring, inject nitrogen gas at the same time, and maintain the above conditions for 1 hour, And implement dehydration of the reaction system. Subsequently, the reflux condenser was connected, and the temperature was raised to 135° C.; then 11.0 g of 100% acrylic acid (hereinafter sometimes referred to as “AA”) and 527 μL (0.55 g, 5.0% by mass of AA) were added from a separate nozzle Tert-butyl peroxybenzoate (hereinafter sometimes referred to as "PBZ") as a polymerization initiator. The dropwise addition time of solution is set, and PBZ is 210 minutes, and AA is 210 minutes, starts to add dropwise 20 minutes after beginning to add PBZ. Also, the dropping rate of each solution was made constant, and the addition of each solution was continuously performed. After the addition of AA was completed, the above r...

Abstract

[Purpose] The purpose of the present invention is to produce a polymer composition with an improved dispersibility for lime soap when used as a detergent and to provide a method for production of the same. [Means of Solution] A laundry detergent or cleaning composition which comprises a polymer composition containing a polymer obtained by polymerizing a polyoxyalkylene-based compound and an unsaturated monomer containing an acid group in the presence of a polymerization initiator, which is characterized by that the polyoxyalkylene-based compound includes 1) a group containing a carbon-carbon double bond, 2) a polyalkylene glycol chain, and 3) one of the groups shown in formulas (1)-(5), and the amount of solvent used at the time of the polymerization is 10 parts or less for 100 parts of the polyoxyalkylene-based compound.

Description

technical field [0001] The present invention relates to a polyoxyalkylene polymer composition, and to a method for its preparation. The present invention also relates to a polyoxyalkylene-based polymer composition polymerized without a solvent or in the presence of a small amount of a solvent, and to a method for its preparation. Background technique [0002] In the past, detergent builders (detergent builders) such as zeolite, carboxymethylcellulose, and polyethylene glycol were often blended with detergents used to wash clothes for the purpose of enhancing the cleaning performance of the detergent. [0003] In addition, in addition to the above-mentioned kinds of detergent builders, polymers have been mixed with detergent compositions as detergent builders in recent years. [0004] For example, polyalkylene glycol-based polymers (see Patent Reference No. 1 for reference) having glycidyl ether-based polymers located in the chain and / or at the chain ends are disclosed for u...
