暗色化変色の外観の減少
表1に記載されているPCMAT低光沢ポリマー添加剤を、ウォーターリングペレタイザー(対照)、又はアンダーウォーターダイフェースペレタイザー(本発明に従う実験)の何れかを用いて調製した。基本供給速度、スクリュースピード、及び溶融温度はそれぞれ、対照及び実験の運転で実質的に同じであった。対照及び実験の両方の運転の間、1ポンドのサンプルを2〜4時間ごとに採取し、視認に必要なサイズ(最大寸法>300μm)を有する黒点のカウント数を提供する自動光学ソーターでチェックした。
温度、空気−対−不活性環境、及び高温での時間を含む、様々な操作条件下での切断用具のブレードに蓄積した低光沢ポリマー添加剤PCMATの変色挙動をシミュレートするために、一連の実験室実験を実施した。試験したPCMATペレットは、実施例1(表1)に記載した成分から製造した。
PCMAT製品を、実施例1(表1)に記載されている材料から調製し、さらに従来の方法(ウォーターリングペレタイザーを使用する)に従い加工した。また、第2のPCMAT製品を、実施例1(表1)に記載されている材料から調製し、さらに本発明の方法(界面温度が低くされ及び酸素への曝露が低減された切断用具、すなわち、アンダーウォーターダイフェースペレタイザーを使用する)に従い加工した。従来のPCMAT製品及び本発明のPCMAT製品をそれぞれ、PC/ABSポリマー配合物(formulation)と混合し、各PCMAT添加剤が光沢を低減する能力について、得られた熱可塑性材料を評価した。処理のバラつきを説明するために、本発明のPCMAT製品の3つの別個の試料を作成し、PC/ABSポリマー配合物と別個に混合した。
以下の表4に示すように、本発明のPCMAT製品を含むPC/ABS熱可塑性ポリマーの光沢度は、従来のPCMAT製品を含むPC/ABS熱可塑性ポリマーの光沢度と実質的に同じであることが観察された。
