Description
ASTM D1396−92
PVBチップを21.0グラムのシートで製造し、50.8mm直径の10.0mm厚さディスクへとヒートプレスする。チップ製造は、シートからカットした50.8mmディスクの積み重ねを金型中で2200N力および185℃で1分間予備加熱する工程と、次にプレス力を185℃で2分間32,000Nに増やす工程と、同じ力の下で7.5分間冷却する工程とを含む。押し出されたシート上にあった何の残存表面パターンもチップには見られない。黄色度指数は10.0mm厚さチップについてASTM D1925−70によって測定した。
Tgは、1Hzでの正接デルタを用いて、ASTM D4065の手順を用いるDMAによって測定する。
ポリ(ビニルブチラール)シートは次の通り製造した。90℃で、平均重合度618の99.5%加水分解された32重量部のポリ(ビニルアルコール)と平均重合度1005の99.5%加水分解された68重量部のPVAとを含む混合物を615重量部の脱塩水に溶解した。この溶液に、1重量部の88%パラ−トルエンスルホン酸と溶解したPVA溶液をpH2にするのに十分な硫酸とを加えた。米国特許公報(特許文献1)に記載された手順を用いて、62重量部のn−ブチルアルデヒドと0.47重量部の70%DOSSとPVA溶液とを90℃に維持した容器中へ装入した。1時間の保持時間の後、スラリーを得て、該スラリーを水酸化ナトリウム溶液で安定化してpHを11に上げた。安定化と同時に、0.07重量部のトランス(登録商標)290表面張力安定化剤を加えた。次にスラリーを脱塩水で洗浄し、冷却した。18.6の残存ヒドロキシル価の顆粒状白色PVB樹脂を得た。フレークを、リットル当たり4グラムのチヌビン(登録商標)Pとリットル当たり8グラムのローウィノックス(登録商標)44B25酸化防止剤とを含有する3GO可塑剤と混合し、押出システム中の滞留時間が約15〜25分であるように押し出した。可塑剤対乾燥フレークの供給速度比は35:100(重量:重量)であった。シート中に100万部当たり10部(ppm)のカリウム濃度をかなえるように、ギ酸カリウム溶液を注入した。スロット・ダイで測定した溶融体温度は210〜215℃であった。シートYIDは5.85であった。
可塑剤対乾燥PVBフレークの供給比が20:100であり、かつ、溶融体滞留時間が25〜40分であったことを除いて、実施例1と同じようにPVBシートを製造した。ダイでの溶融体温度は233℃であった。シート黄色度指数は5.05であった。
界面活性剤としてDOSSの代わりに0.4重量部のラウリル硫酸ナトリウムを使用し、かつ、他の何の表面張力改質剤も添加しなかったことを除いて、実施例1でのようにPVBフレークを製造した。18.6の残存ヒドロキシル価の顆粒状白色PVB樹脂を得た。ここに記載したようなラウリル硫酸ナトリウムで製造したフレークを使用して、実施例1でのようにシートを製造した。スロット・ダイで測定した溶融体温度は210〜213℃であった。シート黄色度は25.05であった。
24:100の3GO可塑剤対乾燥樹脂の供給速度比で、シート中のカリウム・レベルが50ppmであり、かつ、システム中での溶融体滞留時間が25〜40分であったことを除いて、実施例1と同じように比較例C1で記載したフレークを使用してシートを製造した。ダイでの溶融体温度は228〜233℃であった。シート黄色度は53.82であった。
