A moiety with the formula: A-X-Ar.sup.1 -O-Ar.sup.2 reacts in the presence of a catalyst with a moiety of the formula: B-Ar.sup.3 -O-Y to form a linkage of the formula: A-X-Ar.sup.1 -O-Ar.sup.3 -B+Ar.sup.2 -O-Y wherein Ar.sup.1, Ar.sup.2 and Ar.sup.3 are aromatic moieties, X is an activating group, Y is a hydrogen, a trihydrocarbylsilyl, a trihydrocarbyltin, or a carbonyl moiety, and the catalyst is a catalyst capable of abstracting the group Y from the second moiety. The reaction can be used to create a polyarylether polymer.
具有公式:A-X-Ar.sup.1-O-Ar.sup.2 的一半在催化剂的存在下与具有公式:B-Ar.sup.3-O-Y 的一半反应,形成公式的连接:A-X-Ar.sup.1-O-Ar.sup.3-B+Ar.sup.2-O-Y,其中Ar.sup.1,Ar.sup.2和Ar.sup.3是芳香族基团,X是活化基团,Y是氢,三氢基碳基硅,三氢基碳基锡或羰基基团,催化剂是能够从第二个基团中提取基团Y的催化剂。该反应可用于创建聚芳醚聚合物。
