(57) [Summary] An additive for heat stabilization of a thermoplastic resin. A resin additive obtained by treating the surface of inorganic particles such as silica and alumina with tannic acid, then treating with a phenone compound, and further treating the surface with a coupling agent. The resin additive of the present invention imparts thermal stability to the thermoplastic resin at the time of heating and melting, and at the same time, prevents a decrease in IZOT impact strength. |
