2. Description of the Related Art Conventionally, extrusion molding compounds comprising a vinyl chloride resin (hereinafter referred to as PVC), an acrylonitrile / butadiene / styrene resin (hereinafter referred to as ABS) and an inorganic pigment are widely known. AB
When extrusion molding is carried out using an extrusion molding compound in which S and S are mixed in substantially equal amounts, PVC, ABS and inorganic pigments are uniformly melt-mixed in an extruder due to the large difference in melt viscosity between the two. However, there is a disadvantage that plate-out and adhesion of the extruded molten resin in the die, which are considered to be caused by the metal in the inorganic pigment, easily occur. Also,
When a foaming agent was added to and mixed with the compound for extrusion molding and extrusion foaming was performed, plate-out and sticking of the extruded molten resin in the die became more severe, and the long-run property was significantly reduced.

Hereinafter, the present invention will be described in detail. When extruded using the resin composition for extrusion molding of the present invention, PV
ABS, which has a higher melt viscosity than C, is mixed in a large amount at a weight ratio of PVC / ABS = 30/70 to 70/30 with respect to PVC. The average degree of polymerization of PVC is in the range of 500 to 800, since it easily occurs, and this causes plate-out or sticking of the extruded molten resin in the die due to synergistic action with the metal in the inorganic pigment. If the average degree of polymerization is less than 500, the heat resistance and impact resistance provided by ABS are impaired. On the other hand, if it exceeds 800, high torque and high heat generation during extrusion are likely to occur, making it difficult to control,
The appearance of the resulting molded article is poor and the thermal deterioration due to high temperature becomes remarkable, and the inherent properties of the resin are impaired.
