通过钯催化的乙烯与二卤代芳烃的芳基化反应，合成了一系列可溶性和可熔性的聚对苯乙炔衍生物。尽管热重分析表明大多数聚（1，4-亚苯基亚乙烯基）的可熔衍生物具有良好的热稳定性，但在退火时，在熔融状态下发生不可逆转的变化，并伴有各向异性、凝固和不溶解性的丧失。采用镍催化的格氏反应和前驱体法合成了可溶性可熔性聚苯撑。
A wide variety of soluble and fusible derivatives of poly(1,4-phenylenevinylene) were prepared by the Pd-catalysed arylation of ethylene with dihalogenoarenes. Although thermogravimetry indicates good thermal stability of most of the fusible derivatives of poly(1,4-phenylenevinylene), irreversible changes combined with a loss of anisotropy, solidification and insolubility occurred in the molten state on annealing. Soluble and fusible poly(phenyl-1,4-phenylene) was prepared by a Ni-catalysed Grignard reaction and by a precursor route.
