Resin-additive masterbatch

摘要

Disclosed is a resin additive masterbatch which not only is capable of containing a resin additive having a low melting point at a high concentration, but also can be continuously produced without strand breakage and has an improved surface tackiness. The resin additive masterbatch contains, with respect to 100 parts by mass of (A) a crystalline resin, 100 to 900 parts by mass of (B) a resin additive, 0.1 to 10 parts by mass of (C) a metal salt of an organic acid other than fatty acid and 0.1 to 10 parts by mass of (D) a gelling agent, the resin additive masterbatch being characterized in that the above-described (B) resin additive retains a liquid state when melted with heating to 250° C. and then cooled to 80° C. and kept for 30 minutes.
