Abstract

The invention discloses a biodegradable transparent liquid polyester that can be quickly photocured with a mercapto crosslinking agent. The structure is as follows: x+y is 10-100, and theoretically x=y. The invention also discloses a fast photocurable transparent polyester photocurable mixed solution prepared from the biodegradable transparent liquid polyester. The transparent polyester light-curing mixed solution of the invention adopts liquid alkynyl-terminated modified poly(4-methylcaprolactone) as the main material, which has both good biocompatibility and biodegradability of polycaprolactone , and because of the liquid properties at room temperature, the light curing does not require any solvent, achieves zero VOC standards, and the material is transparent, which can smoothly penetrate the curing light.

Description

technical field

[0001] The invention belongs to the field of photocurable polymer materials, in particular to a biodegradable transparent liquid polyester with good biocompatibility that can be quickly photocured with a thiol crosslinking agent, and a preparation method and application. Background technique

[0002] Light-curing material is a curing molding material developed based on light-curing technology. Due to its simple molding and curing method, it has a very wide range of applications in the fields of coatings, dentistry, adhesives, microelectronics and biomaterials. With the promulgation of sustainable development policies and the gradual transfer of photocurable materials to high value-added industries such as biomedicine, traditional acrylate and epoxy photosensitive resins have been unable to meet the requirements, so biodegradable photocurable materials have been widely used. s concern.

[0003] Biodegradable polymer materials are generally divided into two ca...
