Abstract

To provide an alloy resin excellent in the balance between fluidity in melting and heat resistance in curing.SOLUTION: A polymer alloy comprising a polyvinyl chloride (A), a (meth) acrylic resin (B), and a stabilizing agent (C), wherein the stabilizing agent (C) comprises a liquid organotin compound (c1) that is liquid at 20 °C and a powdery organotin compound (c2) that is powdery at 20 °C. It is preferable that the melt flow rate (210 °C., load: 98N) of the alloy resins is 20g / 10 minutes or more, and the deflection temperature under load of the alloy resins is 80 °C. or more.SELECTED DRAWING: None
