Description
一般に、ポリ乳酸樹脂は、とうもろこし澱粉を分解して得られる乳酸をモノマーとして、エステル縮合によって作られるポリエステル系樹脂である。
前記ポリカーボネート樹脂は、下記化学式(1)で表されるジフェノール類を、ホスゲン、ハロゲン化ギ酸エステル、炭酸エステル、およびこれらの組み合わせからなる群より選択される化合物と反応させて製造することができる。
本発明において、アミノ基含有鎖拡張剤は、ポリ乳酸樹脂と結合してポリ乳酸樹脂の粘度上昇を引き起こす。その結果、射出条件を選択することによってポリ乳酸樹脂の分散相への相転移を誘導して、耐熱性、機械的強度、耐加水分解性などが顕著に改善された環境親和的なポリ乳酸樹脂組成物を形成させる役割を果たす。前記アミノ基含有鎖拡張剤は、ポリ乳酸樹脂のカルボキシル基と反応しうるアミノ基を含む化合物である。具体的には、アミノ基含有ポリシロキサン系化合物、またはアミノ基含有ポリオレフィン系重合体が好ましい。
前記アミノ基含有鎖拡張剤は、前記(A)ポリ乳酸樹脂と前記(B)ポリカーボネート樹脂との合計量100質量部に対して、0.01〜5質量部で含まれ、0.5〜3質量部で含まれることが好ましい。前記のような含量の範囲で含まれる場合、適切な溶融押出粘度を有するため、混合成形が容易である。
上記のような組成を有するポリ乳酸樹脂組成物は、ポリ乳酸樹脂相の粘度が上昇する際に、耐衝撃性と共に、さらに粘度を上昇させるように、耐衝撃性改良剤(Impact Modifier)をさらに含むことができる。
米国、ネイチャーワークス社製の4032Dを使用した。
重量平均分子量(Mw)が25,000である、ビスフェノールA系ポリカーボネートを使用した。
粘度が11.2Pa・sであり、アミノ基含量が1.62モル%、主鎖がポリメチルシロキサンであるアミノ基含有鎖拡張剤(Momentive社製)を使用した。
三菱レイヨン株式会社製のメタブレン S−2001(メタクリル酸メチル−アクリル酸n−ブチル−ジメチルシロキサン共重合体)を耐衝撃性改良剤として使用した。
下記表1に示した含量で各成分を混合し、ポリ乳酸樹脂組成物を製造した。ポリ乳酸樹脂50質量部、ポリカーボネート樹脂50質量部、アミノ基含有鎖拡張剤1質量部、および耐衝撃性改良剤5質量部を投入して、通常の二軸押出機で200℃〜230℃の温度範囲で押出した後、押出物をペレット状に製造した。
アミノ基含有鎖拡張剤を2質量部の量で添加したことを除いては、実施例1と同様にポリ乳酸樹脂組成物を製造した。
アミノ基含有鎖拡張剤を3質量部の量で添加したことを除いては、実施例1と同様にポリ乳酸樹脂組成物を製造した。
アミノ基含有ポリ乳酸樹脂の含量とポリカーボネート樹脂の含量とを表1のように変更したことを除いては、実施例3と同様にポリ乳酸樹脂組成物を製造した。
ポリ乳酸樹脂の含量とポリカーボネート樹脂の含量とを表1のように変更したことを除いては、実施例3と同様にポリ乳酸樹脂組成物を製造した。
耐衝撃性改良剤を使用しなかったことを除いては、実施例3と同様にポリ乳酸樹脂組成物を製造した。
アミノ基含有鎖拡張剤を使用しなかったことを除いては、実施例1と同様にポリ乳酸樹脂組成物を製造した。
アミノ基含有鎖拡張剤を10質量部使用したことを除いては、実施例1と同様にポリ乳酸樹脂組成物を製造した。
アミノ基含有鎖拡張剤と耐衝撃性改良剤とを使用しなかったことを除いては、実施例5と同様にポリ乳酸樹脂組成物を製造した。
実施例1〜3および比較例1〜3のペレットを、80℃で4時間乾燥した後、6オンス(1オンス=28.35グラム)の射出能力がある射出成形機を用いて、シリンダー温度230℃、金型温度80℃、成形サイクルを60秒に設定して、ASTMダンベル試験片を射出成形して試験片を製造した。
