Description
a)1種以上の生分解性ポリマーを30〜99.9重量パーセント、
b)1種以上の生体高分子を0〜69.9重量パーセント、および
c)1種以上のコア−シェル型耐衝撃性改良剤を0.1〜15重量パーセント
を含み、上記耐衝撃性改良剤の数平均粒度が250nmを超える、生分解性ポリマー組成物に関する。
アクリル系−メタクリル系共重合体耐衝撃性改良剤を5および7.5重量%含むポリ乳酸95および93.5%のブレンドを、二軸押出機を用いた溶融押出によって形成した。溶融物が確実に均質になるように、押出時の加工温度および溶融温度をポリ乳酸の融点を超える(>152℃)ように維持した。3本ポリッシングロール(three roll stack)および引取装置を用いて押出物をシート(17〜22mil)に成形した。カラーメーターを用いてシートのヘイズ測定を実施し、半球状の頭部を有する2lbの衝撃子を備えたガードナー衝撃試験機を用いてダート落下耐衝撃性測定を実施した。観測されたデータを以下の表1に示す。
