Description
(式中、Rは水酸基で置換されていてもよい炭素原子数1〜18のアルキル基、炭素原子数1〜18のアシル基、または炭素原子数5〜8のシクロアルキル基を表す)で表されるヒンダードアミン化合物0.005〜30質量部が配合されてなることを特徴とするものである。
本発明において用いられるポリ乳酸樹脂としては、ポリ乳酸ホモポリマー、ポリ乳酸コポリマー、ポリ乳酸ホモポリマーとポリ乳酸コポリマーとのブレンドポリマーが挙げられる。また、本発明の効果を損なわない範囲であれば、ポリ乳酸を主体とするブレンドポリマーであってもよい。
(式中、Mはアルカリ金属または亜鉛を表し、xは0〜6の数を表し、yは0〜6の数を表し、zは0.1〜4の数を表し、pはMの価数を表し、nは0〜100の結晶水の数を表す)で表される塩基性炭酸塩が挙げられる。上記ハイドロタルサイト類の使用量は、ポリ乳酸樹脂100質量部に対して、好ましくは0.001〜10質量部、より好ましくは0.01〜5質量部である。
ポリ乳酸樹脂(LACEA H−100;三井化学株式会社製)1.25gおよび下記表1中に記載のヒンダードアミン化合物0.375mgを25mlメスフラスコに加え、塩化メチレンでメスアップした。得られた溶液4mlをシャーレに入れ、溶媒を除去することにより、厚みが70〜90μmのキャストフィルムの試験片を作製した。得られた試験片を用いて、下記に示す評価を実施した。
得られた試験片の耐候性の評価として、スガ試験機株式会社製サンシャイン・カーボンアーク・ウェザオメーター(ブラックパネル温度63℃、120分中に18分間水スプレー有り)にて、360時間毎に試験片表面を観察し、試験片表面にクラックが発生した時間を求めた。その結果を下記表1中に示す。
得られた試験片の結晶化状態について、上記耐候試験中の試験片を360時間毎に取り出して、試験片のHaze(ヘイズ)(%)値で評価した。なお、試験片の結晶化が進むと、ヘイズの値が高くなり試験片は白濁化する。その結果を下記表1中に示す。
下記表1中に記載の配合に基づき、ヒンダードアミン化合物を添加しない以外は上記実施例1および比較例1〜3と同様の方法で試験片を作製して、耐候性評価を行った。その結果を下記表1中に示す。
