A germylene was coplymerized with cyclic alpha, beta-unsaturated ketones at 0ﾟC with various lithium compounds as the catalysts, giving rise to a 1 : 1 alternating copolymer, poly (germanium enolate), with a molecular weight higher than 10^5. The cyclic ketones used were five-, six-, and seven-membered compounds.The ring-opcning polymerization of a spiro gecrmanium enolate proceeds smoothly catalyzed by an anionic initiator, giving rise to a poly (germanium acyclic enolate). The monomer of the spiro germanium enolate is easily prepared in situ by the reaction of a cyclic germylene with methyl vinyl ketone.

以各种锂化合物为催化剂，在0‰的温度下与环α， β -不饱和酮共聚，得到分子量大于10^5的1∶1交联共聚物聚烯酸锗。所使用的环酮是五元、六元和七元化合物。在阴离子引发剂催化下，螺旋形锗烯酸酯的开环聚合过程顺利进行，得到聚无环锗烯酸酯。通过环二甲苯与甲基乙烯酮的反应，可以很容易地原位制备螺烯酸锗单体。
