Abstract

The present disclosure discloses a polymer additive, a flame retardant, a polymer molding material, and a preparation method and a use thereof. The polymer additive comprises aluminum diethylphosphinate and aluminum ethylbutylphosphinate; the polymer additive satisfies a relationship of 0.90 ≤ ΔH ≤ 1.05, wherein ΔH is a dual enthalpy ratio and defined by Equation (1); the polymer additive further satisfies following relationships: 135 °C ≤ T1 ≤ 160 °C, 165 °C ≤ T2 ≤ 185 °C, and 180 °C ≤ T3 ≤ 200 °C; and the Equation (1) is as follows: ΔH = (H2+H3)/H1. The polymer additive has a specific crystal transition state, and a polymer molding material comprising the polymer additive has lower molding shrinkage during the molding process.
