Description
熱可塑性樹脂(A)としてポリカーボネート(PC、帝人化成社製 商品名「パンライト(グレード:1250Y)」、ガラス転移温度Tg:150℃、比重:1.19)と、熱可塑性樹脂(B)としてポリメタクリル酸メチル(PMMA、三菱レイヨン社製 商品名「アクリペット(グレード:VH001)」、ガラス転移温度Tg:110℃、比重:1.19)とをそれぞれ表1に示した所定量ずつ押出機(スクリュー径:φ20mm、スクリュー長/スクリュー径=25)に供給してシリンダー温度280℃にて剪断速度1000sec-1の条件下にて溶融混練して押出機から押出して樹脂組成物を製造した。樹脂組成物は、ポリカーボネートを海部とし且つポリメタクリル酸メチルを島部とした海島構造を有しており、島部の大きさは表1に示した通りであった(混合工程)。得られた樹脂組成物を汎用の熱プレス機を用いて280℃にてプレスすることによって厚みが500μmの樹脂シートに成形した。
熱可塑性樹脂発泡シートを任意の部分において厚み方向に切断し、切断面をSEM(日立ハイテク社製 走査型電子顕微鏡(S−3700N))を用いて、一辺の測定画像範囲が15μmとなる範囲(倍率:10000倍)に拡大して断面写真を得た。
