FLAME RETARDANT COMPOSITION, POLYMER COMPOSITION COMPRISING FLAME RETARDANT COMPOSITION AND PREPARATION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2023/116909

Kind Code:

A1

Abstract:

The present invention provides a flame retardant composition, a polymer composition comprising the flame retardant composition and a preparation method thereof. The flame retardant composition comprises: a brominatedbutadiene-styrene block copolymer; an acid binding agent; and an antioxidant. By applying the flame retardant composition of the present invention, the polymer composition comprising the flame retardant composition and the preparation method thereof, a technical effect of improving the stability of the flame retardant at high temperature is achieved, and the flame retardant composition of the present invention, when used, can effectively balance the flame retardancy and the mechanical properties of the final polymer product.
