were observed in cyclic oligomers and in dispersed polymers based on monomers. Addition of acids and bases promoted transitions between monomeric species and the oligomeric and/or polymeric states. Exchange of constituent monomer units in the cyclic oligomers was observed in the solution state, whereas the polymers obtained as precipitates from CH3CN were not converted to the cyclic oligomers (see scheme)
共价键:在环状低聚物和基于单体的分散聚合物中观察到基于两性离子的共价键。酸和碱的添加促进了单体种类与低聚和/或聚合态之间的过渡。在溶液状态下观察到环状低聚物中组成单体单元的交换,而作为从CH 3 CN的沉淀物获得的聚合物未转化为环状低聚物(参见方案)。
