    Abstract:

    Bis( 3 ̄acetylenephenyl) ̄methylvinylsilazane( SZMV) was synthesized by an aminolysis procedure.
    The physical structure of SZMV was characterized.And then a modified PSA resin ( PSA/ SZMV) was prepared by
    blending PSA and SZMV.A series of test methods were used to investigate the viscosityꎬcuring reactionꎬthermal stabil ̄
    ity and dielectric property of PSA/ SZMV resin.The mechanical properties of quartz fiber reinforced composites were al ̄
    so measured.The results show that with the introduction of SZMVꎬthe viscosity of PSA/ SZMV resin decreases remark ̄
    ablyꎬand the processing technology gets improvedꎬthe thermal stability and dielectric property of cured PSA/ SZMV
    resin slightly decrease.And the flexural strength and interlaminar shear strength of quartz fiber reinforced PSA/ SZMV
    resin composite increase by 45% and 33.6%ꎬrespectively.
