The application discloses a process for making a polymer having pendant side groups comprising:
(i) polymerising an olefinically unsaturated monomer functionalized with (a) an azide group optionally protected by a protecting group, or (b) an alkyne group optionally protected by a protecting group, by living radical polymerization, most preferably RAFT, transitional metal mediated living radical polymerization (TMM-LRP) and/or atom transfer radical polymerization, to produce a polymer intermediate;
(ii) removing, when present, at least a portion of the total number of protecting groups from the polymer intermediate;
(iii) reacting the polymer intermediate with at least one pendant side group moiety functionalised with (a) an alkyne group or (b) an azide group respectively so that the alkyne and azide groups react to attach the pendant side group to the polymer. Processes for making supports comprising pendant side groups, and polymers and supports prepared by the method are also disclosed.
该应用程序披露了一种制备具有侧链基团的聚合物的过程,包括:(i)聚合具有(a)由保护基团选择性保护的
叠氮基团或(b)由保护基团选择性保护的炔基团的烯烃未饱和单体,通过活性自由基聚合,最好是通过RAFT、过渡
金属介导的活性自由基聚合(TMM-LRP)和/或原子转移自由基聚合,以产生聚合物中间体;(ii)从聚合物中间体中至少去除部分或全部保护基团(如有);(iii)将聚合物中间体与至少一种侧链基团修饰的基团反应,所述侧链基团修饰的基团分别具有(a)炔基团或(b)
叠氮基团,以使炔基团和
叠氮基团反应,将侧链基团连接到聚合物上。还披露了制备含有侧链基团的支撑物、以及通过该方法制备的聚合物和支撑物。
