| 摘 要： | 为了获得更低介电常数及介电损耗的材料,采用单官能团氰酸酯改性氰酸酯树脂,研究了单官能团单体对聚合物分子网络结构形成过程、反应过程的流变行为及固化产物性能的影响。研究结果表明,单官能团单体在固化反应初期参与反应比例较小,反应后期才逐步参与反应进入分子网络并促进反应程度的提高,改性树脂体系介电常数为2.8~2.9(7~18 GHz),介电损耗也有一定下降。

| Abstract: | Cyanate ester resins modified by monofunctional cyanate ester had been synthesized. Characterization
of the resins had been carried out including polymer reaction activity, rheology and dielectric performance. Results indicated
that monofunctional cyanate ester partly inserted the polymer network during the final curing stage and improved
the reaction degree of cyanate groups. The cured cyanate ester exhibited a lower dielectric constant ranged
from 2. 8 to 2. 9(7 ~18 GHz) and a lower dissipation factor than those of the cured BADCy resin. |

| Keywords: | Monofunctional cyanate ester Dielectric constant Dissipation factor |
