Beschreibung
Zusammenfassung:	Disclosed are an industrially useful (meth)acrylic polymer particle for use in a plastisol which is excellent in storage stability, particularly under circumstance at 40°C or above, so that it can suppress gelation and maintain a sol state during storage and which can give a shaped article excellent in flexibility and chipping resistance; a method for producing the (meth)acrylic polymer particle; and a plastisol composition made from the (meth)acrylic polymer particle. Specifically disclosed is a method for producing a (meth)acrylic polymer particle, which comprises polymerizing a monomer or monomer mixture (B) to form a polymer (b) in the presence of a polymer (a) obtained by polymerization of a monomer or monomer mixture (A), wherein a glass transition temperature (Tg) of the polymer (a) as calculated from the FOX equation is 90°C or above, a solubility parameter of the polymer (a) is 19.90 (J/cm 3 ) 1/2 or below, and a solubility parameter of the polymer (b) is 20.22 (J/cm 3 ) 1/2 or above.
