Description
好ましい実施形態においては、上記複合体は、上記母材100重量部に対して、0より大きくかつ100重量部以下の上記パラミロン粒子を含む。
好ましい実施形態においては、上記母材は非極性材料である。
好ましい実施形態においては、上記母材は、ポリプロピレンおよびポリ乳酸から選択される。
好ましい実施形態においては、上記複合体は、相溶化剤をさらに含む。
Heidelberg, Germany, 1982, Chapter 4.3 "Gefriertrocken"、DE 43 28 329、または特表2003−529538号公報に記載されている。これらの記載は、本明細書に参考として援用される。
ユーグレナグラシリス粉末((株)ユーグレナ社製)を細胞破砕し、SDSによる清浄およびアセトンでの脱脂を行い、乾燥し、グラインダーにかけることによりパラミロン粒子を得た。母材としてのポリプロピレン樹脂(日本プロピレン社製、製品名「ノバテックPP」)90部、上記パラミロン粒子10部、および相溶化剤としてのマレイン酸変性低分子量ポリプロピレン樹脂(三洋化成社製、製品名「ユーメックス1010」、酸価52)5部を、密閉式混練機(東洋精機社製、製品名「ラボプラストミル」)を用いて、220℃、120rpmで5分間混練し、複合体を得た。なお、ポリプロピレン樹脂およびパラミロン粒子はいずれも、110℃で20時間減圧乾燥したものを用いた。
得られた複合体を曲げ試験に供し、最大応力、弾性率および最大歪みを求め、ポリプロピレン樹脂単独の場合を100%としたときの比率を算出した。最大応力、弾性率および最大歪みの結果を、後述の実施例2と併せて、それぞれ図1〜図3に示す。なお、図1〜図3におけるパラミロン添加率は、母材100部に対する添加部数である。
パラミロン粒子を20部用いたこと以外は実施例1と同様にして複合体を得た。得られた複合体を実施例1と同様の評価に供した。結果を図1〜図3に示す。さらに、得られた複合体の断面を走査型電子顕微鏡(SEM)で観察した。その画像を図4に示す。
母材としてポリプロピレン樹脂の代わりにポリ乳酸(帝人社製、製品名「レイシア100」)を用いたこと以外は実施例1と同様にして複合体を得た。
母材としてポリプロピレン樹脂の代わりにポリ乳酸(帝人社製、製品名「レイシア100」)を用いたこと以外は実施例2と同様にして複合体を得た。
特開2004−231796号公報の実施例1に記載の手順により、木材パルプ由来のセルロースから扁平状のセルロース粒子を得た。このセルロース粒子をパラミロン粒子の代わりに用いたこと以外は実施例1と同様にして、複合体の製造を試みた。しかし、セルロース粒子は分散せず、複合体を得ることができなかった。
Claims (3)
- ポリオレフィンおよびポリ乳酸から選択される母材と、ユーグレナ由来のパラミロン粒子と、酸変性ポリオレフィンで構成される相溶化剤と、を含む、複合体。
- 前記母材100重量部に対して、0より大きくかつ100重量部以下の前記パラミロン粒子を含む、請求項1に記載の複合体。
