双功能基的氰酸酯在催化剂作用下或自催化三聚成环，成为分子量很大的立体网状聚合物－聚氰酸酯，它具有力学强度高、受力变形小、耐热性好、耐高温、易加工、吸水率低、介电常数低等许多特点。双氰酸酯基单体的预聚体可以加入不同量的单功能基单体来调节最后网络的交联密度，预聚体也能与其它树脂混合、改性而得到更理想的性能。氰酸酯聚合物，包括聚氰酸酯和氰酸酯与环氧树酯等的共聚物等，在高密度印刷电路板、大规模固体组件与低电抗结构复合材料、飞机用结构复合材料与卫星、雷达、光纤通信等许多方面有巨大的应用价值。
Bifunctional cyanate ester under the action of a catalyst or autocatalytic trimerization into a ring, a large molecular weight three-dimensional network polymer - polycyanate, which has high mechanical strength, stress deformation, good heat resistance , High temperature, easy processing, low water absorption, low dielectric constant and many other features. The prepolymers of the dicyanate-based monomers can be added with different amounts of monofunctional monomers to adjust the crosslinking density of the final network. The prepolymer can also be mixed with other resins to modify to obtain more desirable properties. Cyanate ester polymers, including polycyanate and copolymers of cyanate ester and epoxy resin, etc. In high-density printed circuit boards, large-scale solid components and low-reactance structure composites, structural composites for aircraft and Satellite, radar, optical fiber communication and many other aspects of great value.
