A low dielectric polymer is obtained by polymerizing a monomeric composition comprising a fumaric acid diester monomer and optionally a vinyl monomer. The polymer having a low dielectric constant and reduced dielectric loss is used as an electrically insulating material in a high frequency band of at least 500 MHz.
低介电聚合物是通过聚合由
富马酸二酯单体和
乙烯基单体组成的单体组合物而获得的。这种聚合物介电常数低,介电损耗小,可用作至少 500 兆赫高频段的电绝缘材料。
