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 diester plasticizer formed from a compound represented by formula (1) shown below. In formula (1), R 1 and R 3 are monovalent hydrocarbon groups that may be the same or different and R 2 is a divalent hydrocarbon group. 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

1 . A vinyl chloride resin composition comprising:
(a) a vinyl chloride resin; and (b) a diester plasticizer formed from a compound represented by formula (1) shown below

where R 1 and R 3 are monovalent hydrocarbon groups that may be the same or different and R 2 is a divalent hydrocarbon group, wherein
(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 %.

2 . The vinyl chloride resin composition of claim 1 , wherein
an amount of (b) the diester plasticizer is from 5 parts by mass to 200 parts by mass relative to 100 parts by mass of (a) the vinyl chloride resin.

3 . The vinyl chloride resin composition of claim 1 , further comprising
(c) a trimellitate plasticizer.

4 . The vinyl chloride resin composition of claim 3 , wherein
a total amount of (b) the diester plasticizer and (c) the trimellitate plasticizer is from 5 parts by mass to 200 parts by mass relative to 100 parts by mass of (a) the vinyl chloride resin.

5 . The vinyl chloride resin composition of claim 3 , wherein
a blending ratio of (b) the diester plasticizer relative to (c) the trimellitate plasticizer, expressed as a mass ratio, is from 1/99 to 99/1.

6 . The vinyl chloride resin composition of claim 1 , wherein
R 1 and R 3 in formula (1) are monovalent aliphatic hydrocarbon groups having a carbon number of 2-24 that may be the same or different, and R 2 in formula (1) is a divalent aliphatic hydrocarbon group having a carbon number of 1-14.

7 . The vinyl chloride resin composition of claim 1 , wherein
R 1 -R 3 in formula (1) each have a straight chain ratio of at least 90 mol %.

8 . The vinyl chloride resin composition of claim 1 , wherein
(x) the base vinyl chloride resin is vinyl chloride resin particles.

9 . The vinyl chloride resin composition of claim 8 used in powder molding.

10 . The vinyl chloride resin composition of claim 8 used in powder slush molding.

11 . A vinyl chloride resin molded product obtainable through powder molding of the vinyl chloride resin composition of claim 8 .

12 . The vinyl chloride resin molded product of claim 11 used as a surface skin of an automobile instrument panel.

13 . A laminate comprising:
a foamed polyurethane molded product; and the vinyl chloride resin molded product of claim 11 .
