Polyester resin containing biomass-derived monomer, method for producing the same, and powder coating composition containing the resin

摘要

The present invention relates to a polyester resin containing a biomass-derived monomer, a method for producing the same, and a powder coating composition containing the resin. More specifically, by including a unit derived from biomass-derived anhydrous sugar alcohol or a derivative thereof having improved reactivity as a repeating unit, the problem of exhausting petroleum resources, which is a finite resource, can be solved, and it is environmentally friendly and highly It relates to a polyester resin having heat resistance and capable of remarkably improving the weather resistance and flexibility of a coating film when applied to a powder coating, a method for producing the same, and a powder coating composition containing the resin. is there.
