FOAMABLE ACRYLIC RESIN PARTICLE, FOAMED ACRYLIC RESIN PARTICLE AND METHOD FOR PRODUCING THE SAME

To provide a foamed acrylic resin particle that can early stabilize the shape of a foamed particle molding and a method for producing the same, and a foamable acrylic resin particle that is a base material for the foamed acrylic resin particle.SOLUTION: A foamable acrylic resin particle comprises a resin particle body composed of an acrylic resin as base resin, and a foamer. The resin particle body has its surface combined with a fatty acid amide having a melting point of 60°C or higher and 140°C or lower. The amount (x) of the fatty acid amide combined therewith is 0.01 pt.mass or more and less than 0.3 pt.mass relative to 100 pts.mass of the resin particle body.SELECTED DRAWING: Figure 1 【課題】発泡粒子成形体の形状を早期に安定させることができるアクリル系樹脂発泡粒子及びその製造方法、並びにこのアクリル系樹脂発泡粒子を得るための発泡性アクリル系樹脂粒子を提供する。【解決手段】発泡性アクリル系樹脂粒子には、アクリル系樹脂を基材樹脂とする樹脂粒子本体と、発泡剤と、が含まれている。樹脂粒子本体の表面には融点６０℃以上１４０℃以下の脂肪酸アマイドが付着している。脂肪酸アマイドの付着量（ｘ）が樹脂粒子本体１００質量部に対して０．０１質量部以上０．３質量部未満である。【選択図】図１
