Anionic homo- and copolymerization of -diethynylbenzene in the presence of n-BuLi in polar solvents was carried out. The use of hexamethylphosphortriamide (HMPA) makes it possible to synthesize a completely linear soluble polymer that does not have branching and phenylene fragments. A copolymer of -diethynylbenzene with diphenyldiacetylene was synthesized. Homo- and copolymers of -diethynylbenzene have high thermo- and thermo-oxidative stability. By the interaction of side reactive ethynylphenylene groups with various reagents, it is proposed to synthesize clusters along the conducting chain of poly--diethynylbenzene. Due to presenting C≡CH side groups, boron, copper, and cobalt derivatives were synthesized. It is shown that not all theoretically possible stereoisomers can be formed as a result of the polymerization. The application of -diethynylbenzene polymers for the modification of industrial samples of epoxy novolac resin, oligoester acrylates, and carbon fibers has been demonstrated.
在极性溶剂中,以正丁基锂为引发剂,进行了对二乙炔基苯的阴离子均聚和共聚反应。使用六甲基磷酰胺(HMPA)能够合成一种完全线性的可溶性聚合物,该聚合物没有支链和亚苯基片段。合成了对二乙炔基苯与二苯基二乙炔的共聚物。对二乙炔基苯的均聚物和共聚物具有高的热稳定性和热氧化稳定性。通过侧链反应性乙炔基苯基与各种试剂的相互作用,有人提出沿聚对二乙炔基苯的导电链合成簇状物。由于存在C≡CH侧基,合成了硼、铜和钴的衍生物。结果表明,并非所有理论上可能的立体异构体都能通过聚合反应形成。已证明对二乙炔基苯聚合物在环氧酚醛清漆树脂、低聚酯丙烯酸酯和碳纤维等工业样品改性中的应用。
