An aromatic ring polymer wherein adjacent aromatic ring skeletons cannot have a conformation positioned on a single plane due to mutual steric hindrance of the adjacent aromatic ring skeletons and is represented by the following formula (1):
X-A-Y-B
n
(1)
wherein X and Y may be the same or different, and each represent a monocyclic or heterocyclic bivalent aromatic group which may be substituted with R; A and B may be the same or different, and are each a single bond or a substituent which can contain an aromatic group; and n is an integer of 5 to 1000000. This polymer has a low dielectric constant, and is excellent in heat resistance and strength.
这是一种芳香环聚合物,其中相邻的芳香环骨架由于相互的立体位阻而不能具有单一平面构象,其
化学式表示为(1):X-A-Y-Bn(1),其中X和Y可以相同或不同,分别代表可以被R取代的单环或杂环二价芳香基团;A和B可以相同或不同,分别为单键或含有芳香基团的取代基;n为5到1000000的整数。这种聚合物具有低介电常数,具有良好的耐热性和强度。
