Abstract

The invention discloses a ditellurium-containing degradable polycarbonate polyurethane and a preparation method thereof. The ditellurium-containing polycarbonate polyurethane molecular chain contains -Te-Te-groups and has repeating units of the following structure: Or wherein: m and n are any integers from 2 to 8; T is a chain segment of polycarbonate diol; G is a structural unit of diisocyanate. The structure of the degradable polycarbonate polyurethane containing ditellurium provided by the present invention is controllable, the tellurium content is adjustable, and the molecular structure of the obtained polymer is determined; in the present invention, ditellurium diol or ditellurium diamine is used as a chain extender The ditellurium group was introduced into the polymer main chain, and the prepared polymer has redox responsiveness, good ability to scavenge oxygen free radicals and anti-inflammatory effect at the same time.

Description

technical field

[0001] The invention relates to the technical field of ditellurium-containing polymers, in particular to a ditellurium-containing degradable polycarbonate polyurethane and a preparation method thereof. Background technique

[0002] In recent years, cardiovascular disease has become the number one killer threatening human life and health. Among conventional treatment methods, taking and injection of drugs, interventional therapy, etc. have become effective means and are widely used by people. The interventional treatment methods often require people to modify the intervention materials to ensure special effects such as anti-inflammation, anti-coagulation and scavenging oxygen free radicals.

[0003] Tellurium is a metalloid existing in the periodic table of elements, and studies have shown that the bond energy of the ditellurium bond is only 126kJmol -1 , this feature gives ditellurium bonds many unique properties. In recent years, Xu Huaping's research gro...
