Title:

PBAT RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2017/121223

Kind Code:

A1

Abstract:

The present invention discloses a PBAT resin composition. The PBAT resin composition comprises the following components: (a) poly(butylene adipate-co-terephthlate); and (b) iron; wherein the iron is provided at a weight content of 1 ppm to 500 ppm based on the total weight of the PBAT resin composition. By adding an iron-containing compound into the composition and controlling the iron content of the composition to be within a range of 1 ppm to 500 ppm, the present invention can slow a reaction speed of an aromatic structure in the PBAT resin under humid and hot conditions. The PBAT resin composition prepared according to the present invention exhibits a change in b value of less than 2 after being subjected to aging in boiling water for 24 hours and 48 hours, indicating a markedly improved color stability resistance against aging in boiling water.
