Condensation of fluoro-substituted and silyl-substituted monomers provides polymers suitable for use, e.g., as engineering polymers. A monomer composition is condensed in the presence of a basic catalyst. The monomer composition contains a compound of formula F—X—F and a compound of formula (R

comprises H or an organic moiety.
含氟和硅烷取代单体的聚合物可以作为工程聚合物使用。在碱性催化剂的存在下,将单体组合物进行缩合反应。单体组合物包含化合物F—X—F和化合物(R1)3Si—Z—Si(R1)3,并形成交替的X—Z聚合物链和硅氟化物副产物。X的公式为-A(-R2-A)n-;每个A是SO2,C(═O)或Het;R2是有机基团;n为0或1;Het是芳香族氮杂环;Z的公式为-L-R3-L-;每个L是O,S或N(R4);每个R3是有机基团,R4包括H或有机基团。
