Embodiment 1 3

[0036] The synthesis of embodiment 1 trichloroborazine (TCB)

[0037] In a 500ml four-necked flask equipped with a nitrogen conduit, a stirrer, a thermometer, and a condenser tube, after several cycles of dehumidification and oxygen removal by vacuuming and passing nitrogen, add NH 4 Cl powder 32g (0.30mol) and toluene 300ml, and vigorously stirred to form a suspension, heated to 110 ° C, slowly into the four-necked flask BCl 3 Gas, heat preservation reaction at this temperature for 10h, and cool to room temperature. Then use shleck technology to filter under nitrogen protection, transfer the filtrate to a rotary evaporator, and distill off the solvent under reduced pressure to obtain colorless needle-shaped crystals of trichloroborazine (TCB). The infrared spectrum is as follows: figure 1 shown.

Abstract

The invention discloses a borazine aryne resin and a preparation method thereof. The borazine aryne resin is structurally characterized in that the polymer molecular chain contains borazine and aryl alkynyl structures. The preparation method of the resin comprises the following steps: on the basis of taking diacetylene-benzene, boron trihalide and ammonium chloride or organic primary amine as raw materials, reacting in three steps in the presence of an inert gas so as to synthesize the borazine aryne resin. The preparation method is simple in process, convenient to operate and short in reaction time, the process condition is easy to control, and the aftertreatment process is simple; the borazine aryne resin is reddish brown viscous fluid or faint yellow solid, and can be solidified in a light and thermal polymerization mode; the borazine aryne resin has excellent thermal resistance and low dielectric property, can be used for preparing an advanced resin-based composite material, can be also used as a low dielectric material, and can be widely applied to the fields of aerospace and electronic information.

Description

technical field [0001] The invention relates to a special functional polymer material, in particular to a borazine aryne resin and a preparation method thereof. Background technique [0002] With the development of information technology, the feature size of ultra-large-scale integrated circuits (ULSI) is shrinking according to Moore's law, and the demand for low dielectric constant materials has attracted people's attention; The performance of wave materials puts forward higher requirements. However, the dielectric properties and high temperature resistance of traditional organic resins can no longer meet the needs of hypersonic aircraft, VLSI and chips. [0003] Polyaryl acetylene resin has good molding process performance, excellent dielectric properties and excellent high temperature resistance. Polyaryl acetylene resin is used as a high temperature resistant wave-transmitting material in the aerospace field. Borazine has a stable structure, and compounds containing bo...
