摘要：NOVELTY - The invention discloses a new kind of carborane- silane- phenylacetylene polymer and the method for preparing the same. Said polymer employs methylchlorosilane, phenylacetylene, carborane and organiclithium agent as raw material, anhydrous tetrahydrofuran (THF) as dissolvent and preparing with protection of nitrogen. The invention moderates molar ratio between simple function group ethynyl compound and carborane to easily control molecular weight of polymer, crosslinking density and carborane content, and realizes purpose of adjustable polymer property. The invention is characterized by simple process and easy operation. The prepared polymer forms thermostable thermosetting material with excellent thermal oxidation performance by heat, light and chemical initiation. Said thermosetting material can be produced to ceramic structure by heating on air or inactive gas. The polymer can be used as base resin and thermo-stable coating for advanced complex material and for preparing ceramic pioneer body.
