ENCAPSULATED PHENOLIC ANTIOXIDANTS

摘要

The present invention pertains to a concentrated aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a polymer carrier, a non-polar organic phenolic antioxidant and a surfactant. The present invention also pertains to a process for the preparation of said concentrated aqueous polymer dispersion, to a polymer powder obtainable from said concentrated aqueous polymer dispersion, to a composition comprising an organic material and said concentrated aqueous polymer dispersion or said polymer powder and to the use of said concentrated aqueous polymer dispersion or said polymer powder as stabiliser for organic material.
