近年来国际上对共轭高分子进行了大量的研究,对于在主链上合有碳氮共軛双鍵的聚腈文献上见到的尚属不多。已报导的有等以氯化锌、四氯化钛等将乙腈、苯甲腈进行聚合,田畑、祖父江等将丙烯腈在乙烯溶液中用γ射线辐照聚合,Lunin将尿素、碳酸铵、碳酸钠等无机盐在氯化鋅、氯化铵存在下缩合聚合都能得到聚腈。本文报导在氯化锌及金属氧化物(ZnO,CuO,Al_2O_3,TiO_2等)存在下从丙烯腈制得具有(?)共軛双键聚合物的初步研究結果。 将精制的丙烯腈分别与氯化鋅及氧化物(ZnO,CuO,Al_2O_3,TiO_2等)按1:1—4:1重量比在封管中于80—300℃保持5—250小时进行聚合。反应完毕后,将产物以沸蒸馏水
In recent years, a large number of studies on conjugated polymers have been carried out in the world. However, there is not much literature on the literature of polycarbonitriles with carbon-nitrogen conjugated double bonds in the main chain. It has been reported that zinc chloride, titanium tetrachloride and the like are used to polymerize acetonitrile and benzonitrile. Polymerization of acrylonitrile in an ethylene solution by gamma rays, such as azulene, grandfather and the like, is carried out. Lunin converts urea, ammonium carbonate, Sodium and other inorganic salts in the presence of zinc chloride, ammonium chloride condensation polymerization can be obtained poly nitrile. In this paper, we report the preliminary results of the production of (?) Conjugated double bond polymers from acrylonitrile in the presence of zinc chloride and metal oxides (ZnO, CuO, Al 2 O 3, TiO 2, etc.) Purification of acrylonitrile with zinc chloride and oxides (ZnO, CuO, Al 2 O 3, TiO 2, etc.) in 1: 1 to 4: 1 by weight ratio in sealed tubes at 80-300 ° C for 5-250 hours. After the reaction was completed, the product was distilled off in boiling water
