摘要：A novel borazine-containing arylacetylene resin (PBZA) has been synthesized in high yield through condensation reaction between B,B',B"-trichloroborazine and arylacetylene Grignard reagent, which are potential candidates as low dielectric constant material for microelectronic packaging and also radio and microwave frequency substrate. The PBZA is a brown viscous liquid and soluble in a variety of common solvents. PBZA could be cured by polymerization of alkynyl groups to form organic-inorganic hybrid structure containing borazine ring and aromatic rings with exothermic polymerization temperature in the 190-250 degrees C range and the structure exhibits great dependence on the substituent on borazine in PBZA. The cured PBZA exhibits high thermal stability with char yield up to nearly 80% at 1000 degrees C and great chemical stability. Especially, the cured PBZA shows low dielectric constant (ca. 2.7) and extremely low dielectric loss (<0.002). The cured PBZA under higer annealing temperatures exhibits lower dielectric constant and dielectric loss. (C) 2014 Elsevier B.V. All rights reserved.
