Preparation method and separation method of low polymerization cyclic polymer

The invention provides a preparation method of a low polymerization cyclic polymer, and the method comprises the following steps: (1-1) in an organic solvent A, terephthaloyl chloride and 1,4-butanediol undergo esterification reaction under the action of

A practical synthesis of the cyclic butylene terephthalate trimer

This paper described a practical synthetic approach for the cyclic butylene terephthalate trimer (7). The key step was a ring-closing metathesis, using Grubbs' second-generation catalyst to form the macrocyclic ring. The advantages of this procedure included short reaction steps, simple operations and good yields.
