<P>PROBLEM TO BE SOLVED: To provide a polymer particle for a press molded body, which can impart high thickening effects to a compound even added by small amounts, without deteriorating working efficiency at handling, and without impairing water resistance of the press molded body. <P>SOLUTION: The polymer particle for a press molded body comprises 94-99.5 pts.wt. of a polymer derived from an aliphatic (meth)acrylate-based monomer and 0.5-6 pts.wt. of a 3-10C aliphatic carboxy group-containing vinylic monomer, and has a weight-average molecular weight of 200,000-700,000. <P>COPYRIGHT: (C)2012,JPO&INPIT |
