Title
(JA) 機能性スキン層を有する発泡ポリスチレン粒子およびその製造方法、ならびにそれを用いた機能性発泡ポリスチレン成形物およびその製造方法
Abstract
(JA)

発泡ポリスチレン粒子の表面に、酢酸ビニル系樹脂ベースの機能性スキン層が形成された、発泡ポリスチレン粒子、およびその製造方法、ならびにそれらの利用に関する。本発明の発砲ポリスチレン粒子によれば、スキン層を構成する酢酸ビニル系樹脂による、軽量性、保温断熱性、寸法安定性、緩衝性、吸音性などの特性、および優れた低温融着性と気密性、防水性、耐久性が同時に得られるのみならず、所望により、酢酸ビニル樹脂に、難燃剤、撥水剤、抗菌剤、着色剤、香料などの様々な機能性添加剤を加えることにより、簡単に様々な機能性を発砲ポリスチレン粒子に与えることができる。
