Acrylic acid (salt) polymer, its production process and uses |
摘要 |
<p>The present invention provides: an acrylic acid (salt) polymer, which has a low molecular weight and a narrow molecular weight distribution and can display excellent dispersibility, or which has a high molecular weight and a high water solubility; a production process that enables easy production of this polymer; and an acrylic acid (salt) polymer composition comprising this polymer. The acrylic acid (salt) polymer is an acrylic acid (salt) polymer of which not less than 1 weight % of the entirety is accounted for by an acrylic acid (salt) polymer having a specific terminal structure. In addition, the production process for an acrylic acid (salt) polymer comprises the step of carrying out polymerization of a monomer component including an acrylic acid (salt), wherein an acrylic acid (salt) having a furfural content of 200 to 400 weight ppm is used as at least a portion of the acrylic acid (salt) in an amount of not smaller than 10 weight % of the entire monomer component.</p> |
