Abstract:A series of polybenzoxazine (PBZ)/resorcinarene composites with low dielectric constants were prepared by the thermal curing of a siloxane‐containing benzoxazine (P‐aptmds) with C‐methylcalix[4]resorcinarene (CMCR). CMCR with active hydroxyl groups could serve to lower the thermal curing temperature of P‐aptmds. The results of differential scanning calorimetry (DSC) showed that the peak exothermic temperature of P‐aptmds decreased from 262°C to 192°C. The introduction of CMCR increased the crosslinking density… Show more
