The article was titled 《Preparation of poly(silicon-phenyl-arylacetylene) resin by polymerizing dialkynylarylenes and phenylsilane catalyzed by alkali metal hydroxide》. The information in the text is summarized as follows:
A new method for preparing silicon-containing Ph arylacetylene resin (SPAR) has been developed using aromatic dialkyne derivatives and 1,4-bis(dimethylsilyl) benzene as raw materials in a one-step reaction in air. In addition, NaOH, a nontransition metal catalyst, was used to achieve high yield polymerization The exptl. conditions affecting polymerization, including monomer species, catalyst dosage, polymerization time, reaction solvent and temperature were investigated. Gel permeation chromatog., NMR and Fourier transform IR spectroscopy were used to determine the mol. weight and structure of the SPARs. Thermogravimetric anal. revealed their thermal stability, and the results indicated that most of them had good thermal stability. This polymerization method that employs simple preparation method, less expensive catalysts, and less complicated posttreatment method will provide an efficient preparation of functional SPARs. In the experiment, the researchers used 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Related Products of 74029-40-6)
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. Related Products of 74029-40-6 They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however.
