Abstract

New oligomeric compounds containing long aliphatic chains with polar nitrogen-containing terminal groups are successfully used as clay modifiers in a one-step process for producing polymer-aluminosilicate nanocomposites. Polymer-aluminosilicate nanocomposites based on medium density polyethylene containing modifiers of various chemical structures (the length of the modifier aliphatic chain and the structure of the terminal polar group are varied) are presented. The influence of the method on the structure and physicomechanical properties of the composites is studied. It is shown that the use of oligomeric modifiers with an aliphatic chain length of 80–90 carbon atoms provides a more pronounced reinforcement of the composite. At the same time, the physicomechanical characteristics of the composite are more significantly affected by the length of the modifier aliphatic chain and the structure of the composite is influenced by the structure of the terminal polar group of the modifier.

摘要

包含长脂肪族链和极性含氮末端基团的新型低聚化合物已成功用于一步法生产聚合物-铝硅酸盐纳米复合材料的粘土改性剂。提出了基于中密度聚乙烯的聚合物铝硅酸盐纳米复合材料，其中包含各种化学结构的改性剂（改性剂脂族链的长度和末端极性基团的结构均发生变化）。研究了该方法对复合材料结构和物理力学性能的影响。结果表明，脂族链长为80-90个碳原子的低聚改性剂的使用可为复合材料提供更明显的增强作用。与此同时，
