Abstract

The invention discloses a polylactone preparation method. The method includes the specific steps that ring opening of cyclic lactone monomer or cyclic carbonate monomer is initiated by initiator alcohol or initiator amine, ring opening polymerization of micromolecule monomer is initiated under the catalyzing action of organic catalysts, and polylactone is obtained. Compared with an existing catalyzing system, the polylactone preparation method has the obvious advantages of being moderate, efficient, wide in source range, simple in synthesis, multiple in category, wide in range, free of metal and the like.

Description

technical field

[0001] The invention belongs to the technical field of organic catalysis and polymer materials, and specifically relates to a polylactone method. Background technique

[0002] Polylactic acid, polyε-caprolactone, polyδ-valerolactone and polycarbonate are biodegradable and bioabsorbable polymer materials, which can be easily blended with other polymer materials to improve the degradability of polymer materials new. As a fully degradable and environmentally friendly material derived from renewable resource crops, it has attracted widespread attention and research from people all over the world.

[0003] There have been a lot of researches on the preparation methods of polylactones, among which ring-opening polymerization with cyclic lactones is a method that has been studied more. As far as the catalysts for the ring-opening polymerization of lactide are concerned, in the early stage, metal-containing catalysts were used to carry out ring-opening polymerizati...
