MASTERBATCH, AND METHOD OF PREPARING POLYAMIDE RESIN COMPOSITION USING MASTERBATCH |
摘要 |
Capable of being provided are [1] a master batch comprising polyamide (X) comprising a diamine unit containing 70 mole % or more of a metaxylylenediamine unit and a dicarboxylic acid unit and an alkali compound (A), wherein an average particle diameter of the alkali compound (A) contained in the master batch is 50 µm or less; a contained number of particles having a particle diameter of exceeding 80 µm in 5 square millimeter of a cross section of the master batch is 1.5 particle or less; and a sum (m) of values obtained by multiplying a mole concentration of an alkali metal atom and a mole concentration of an alkaline earth metal atom each contained per g of the master batch by valencies thereof respectively is 60 µmol/g or more and 1710 µmol/g or less and [2] a production process for a polyamide resin composition prepared by making use of the master batch described in the above item [1]. Making use of the master batch of the present invention makes it possible to provide a polyamide resin composition which has a good appearance and a good color tone and which forms less gels in mold processing. |
