阅读说明：本技术 用于光泽度和表面光洁度改性的官能化丙烯酸系加工助剂 (Functionalized acrylic processing aids for gloss and surface finish modification ) 是由 K·R·尤卡 D·A·芒茨 J·M·莱昂斯 于 2017-03-23 设计创作，主要内容包括：一种减小光泽度的方法,该方法得到一种聚氯乙烯(PVC)部件,该部件表现出减小的表面光泽度,其中PVC或其他热塑性树脂部件包含：PVC树脂、一种或多种加工助剂以及任选的至少一种抗冲改性剂,所述加工助剂包含至少一种基础聚合物,并且所述加工助剂中的一种或多种用基于加工助剂总重的约0.5重量％至约35重量％的反应性环氧基、羟基或羧酸官能团官能化。所述PVC或其他热塑性树脂部件与加工助剂未官能化的类似PVC部件相比,在85度以下的角度测得的光泽度减小至少5点。(A method of reducing gloss resulting in a polyvinyl chloride (PVC) part exhibiting reduced surface gloss, wherein the PVC or other thermoplastic resin part comprises: PVC resin, one or more processing aids comprising at least one base polymer, and one or more of the processing aids functionalized with reactive epoxy, hydroxyl, or carboxylic acid functional groups in an amount of from about 0.5 to about 35 weight percent, based on the total weight of the processing aid, and optionally at least one impact modifier. The PVC or other thermoplastic resin part has a reduction in gloss measured at an angle below 85 degrees of at least 5 points as compared to a similar PVC part that has not been functionalized with a processing aid.)
