Abstract

Provided is a vinyl chloride resin composition that can provide a molded product having superior flexibility at low temperatures. The vinyl chloride resin composition includes (a) a vinyl chloride resin and (b) a dodecanedioic acid diester. Moreover, (a) the vinyl chloride resin includes (x) a base vinyl chloride resin in an amount of from 70 mass % to 100 mass % and (y) vinyl chloride resin fine particles in an amount of from 0 mass % to 30 mass %.

First claim

The invention claimed is:

1. A vinyl chloride resin composition comprising:
(a) a vinyl chloride resin,
(b) a dodecanedioic acid diester; and
(C) a trimellitic acid ester, wherein
a total amount of (b) the dodecanedioic acid diester and (c) the trimellitic acid ester relative to 100 parts by mass of (a) the vinyl chloride resin is from 5 parts by mass to 200 parts by mass,
a blending ratio of (b) the dodecanedioic acid diester relative to (c) the trimellitic acid ester, expressed as a mass ratio, is from 50/50 to 99/1,
(a) the vinyl chloride resin includes (x) a base vinyl chloride resin in an amount of from 70 mass % to 100 mass % and (y) vinyl chloride resin fine particles having an average particle diameter of at least 0.1 pm and no greater than 10 pm in an amount of from 0 mass % to 30 mass %, and
wherein the vinyl chloride resin composition is free of a sebacate.

2. The vinyl chloride resin composition of claim 1 , wherein
(x) the base vinyl chloride resin is vinyl chloride resin particles having an average particle diameter of at least 50 μm and no greater than 500 μm.

3. The vinyl chloride resin composition of claim 2 used in powder molding.

4. The vinyl chloride resin composition of claim 2 used in powder slush molding.

5. A vinyl chloride resin molded product obtainable through powder molding of the vinyl chloride resin composition of claim 2 .

6. The vinyl chloride resin molded product of claim 5 used as a surface skin of an automobile instrument panel.

7. A laminate comprising:
a foamed polyurethane molded product; and
the vinyl chloride resin molded product of claim 5 .
