The present invention relates to a poly(p-xylylene)-based polymer having a low dielectric constant suitable for low loss dielectrics (LLD), and an insulating material, a printed circuit board and a functional element using the same. More particularly, the poly(p-xylylene)-based polymer includes at least one repeat unit expressed by the following formula (1):
wherein, at least one of R1, R2, R7 and R8 is independently substituted or unsubstituted C6-C20 aryl;
the rest of R1 to R8 are each and independently H, substituted or unsubstituted linear C1-C3 alkyl, or substituted or unsubstituted branched C1-C3 alkyl; and
n is an integer of 400 to 900.
本发明涉及一种基于聚(对二甲苯)的聚合物,具有低介电常数,适用于低损耗介电材料(LLD),以及使用该聚合物的绝缘材料、印刷电路板和功能元件。更具体地说,聚(对二甲苯)基聚合物包括至少一个由以下公式(1)表示的重复单元:
其中,R1、R2、R7和R8中的至少一个是独立的取代或未取代的C6-C20芳基;R1到R8的其余部分分别且独立地是H、取代或未取代的线性C1-C3烷基,或取代或未取代的支链状C1-C3烷基;n是400到900的整数。
