Poly(dipropyleneglycol)phenyl phosphite Usage And Synthesis

Description

Poly(dipropyleneglycol)phenyl phosphite is a colorless transparent liquid also known as Phosphorous acid, oxybis(1-methyl-2,1-ethanediyl). It is a high-molecule phosphite ester antioxidant with very high phosphorus. It has a stronger ability to decompose hydroperoxide(ROOH) than common phosphite.

Uses

Poly(dipropyleneglycol)phenyl phosphite is an antioxidant. It has a free hydroxyl number of approximately 20mg KOH/g. It can be used to hinder phenolic antioxidants and UV absorbers to have a synergist effect. This compound is widely used as a secondary antioxidant in many polymers, including PVC Film, Polyurethane Film and glue, Rubber and Latex, Rosin and unsaturated resins, and PUR Coatings.
