Resin Additive

摘要

The present invention provides a resin additive obtained by subjecting inorganic particles of silica or alumina to surface treatment with tannic acid and further subjecting them to surface treatment with a coupling agent, or subjecting inorganic particles to surface treatment with tannic acid and then subjecting them to surface treatment with a phenone compound or saccharides, followed by further subjecting them to surface treatment with a coupling agent. The above resin additive has an effect to provide a thermoplastic resin with heat stability in heating and melting the resin and prevent a reduction in the IZOD impact strength.
