Summary: The study found that blending a small amount of HB-PED230 can effectively reduce the curing temperature of CE resin, while improving the bending strength and impact strength. Additionally, it was observed that as the amount of HB-PED230 increased, the flexural strength and flexural modulus of the copolymers were improved.

Summary: In this study, a nonmetallic catalyst, 4-(4-aminophenoxy) phthalonitrile (PN-NH2), was used to reduce the curing temperature and time of cyanate ester (CE) resin. The addition of PN-NH2 significantly decreased the characteristic curing temperatures and activation energy of the CE resin. The cured resins with PN-NH2 showed superior mechanical and dielectric properties while maintaining reduced curing temperatures.

Summary: Epoxy-based silsesquioxane (EOVS) was oxidized from octavinyl silsesquioxane (OVS) and used to prepare E51/BADCy/EOVS nanocomposites with epoxy resin and cyanate ester. The addition of EOVS resulted in a lower dielectric constant due to increased free volume. The nanocavities introduced by POSS were confirmed to increase the free volume, and the crosslinking density was determined to understand the spatial structure of the nanocomposites. The E51/BADCy/EOVS nanocomposites exhibited a surprising decrease in dielectric constant and dielectric loss, making them promising candidates for the microelectronics industry.

Summary: The dielectric constant of the matrix can be reduced by adding a small amount of POSS due to its unique cage skeleton structure and the air trapped in the caves. The compatibility between EPPOSS and BADCy as well as BA-a was enhanced through curing processing and copolymerizing. The addition of higher quantities of EPPOSS resulted in lower dielectric constants, improved storage modulus, and T(g)s, as well as increased toughness and thermal stability through increased crosslinking density and inorganic Si-O-Si framework.

Summary: In this study, a novel fluorinated poly(aryl ether nitrile) (PFPEN) was synthesized and added to cyanate ester (CE) resin to enhance its toughness and mechanical properties. The addition of PFPEN facilitated the curing reaction of the resin, resulting in improved tensile strength, impact strength, lap shear strength, and peel strength. However, the decrease in crosslinking density may affect the lap shear strength at high temperature and the glass transition temperature (Tg) of the material.
