摘要：NOVELTY - A propargyl ether modified silicon-containing aryne resin, which is prepared by stirring and reacting 5-50 pts.wt. of propargyl ether compound and 50-95 pts.wt. of silicon-containing aryne resin having a polymerization degree of 2-6 for 0.5-4.0 hours at 90-180 degrees C in the presence of inert gas, is new. USE - The propargyl ether modified silicon-containing aryne resin is useful for industrial and commercial applications. ADVANTAGE - The propargyl ether modified silicon-containing aryne resin has good processability, low softening point, and low melting resin viscosity. Moreover, it can be dissolved in multiple solvent and is convenient to use; where the resin and the fiber have excellent viscosity. Additionally, the resin can be cured under the action of heat, radiation or light to form high crosslinked polymer; where no micromolecule is discharged during the process of curing. DETAILED DESCRIPTION - A propargyl ether modified silicon-containing aryne resin, which is prepared by stirring and reacting 5-50 pts.wt. of propargyl ether compound and 50-95 pts.wt. of silicon-containing aryne resin having a polymerization degree of 2-6 for 0.5-4.0 hours at 90-180 degrees C in the presence of inert gas; where the propargyl ether compound is of formula HC triple bond CH2O-Ar-OCH2C triple bond CH; the silicon-containing aryne resin is mainly prepared by the compound of formula Ar1-C triple bond CMgX and/or the compound of formula XMgC triple bond C-Ar2-C triple bond CMgX, and dihalide silicane; and the dihalide silicane is a compound of formula X-((R1)-Si-(R2))-X; is new. Ar=benzene derivative of Formula (I) or (II); where Y is CH3CCH3, CF3CCF3, O, CH2, S, carbonyl, or sulfone; Ar1=monosubstituted aromatic ring; Ar2=disubstituted aromatic ring; X=Cl, Br, or I; and R1 and R2=respectively and independently selected from one of H, 1-6C alkyl, and phenyl.
