含硅芳炔单体的流变性及聚合物热分解
Rheological property of silicon-containing arylacetylenes and thermal degradation of their polymers
摘要
Abstract
The rheological properties of phenyl(triphenylethynyl)silane(PTPES), vinyl(triphenylethynyl)silane(VTPES), diphenyl(diphenylethynyl)silane(BPBPES) three monomers and their polymers(TSAR) were studied by rheometer. At the same time, the degradation reaction kinetics of TSAR was analyzed and the degradation mechanism was also proposed by kinetic theory. The results show that three monomers have an excellent processability with beyond 150 ℃ process window by rheological analysis. Char yield obtained by TG was about 70% at 800℃. The reaction order was 4 and reaction activation energy was E=131.2 kJ/mol by 8 different kinetic analysis methods.关键词
