Abstract
Official abstract text for this publication.
Provided is a vinyl chloride resin composition for powder molding with which it is possible to form a vinyl chloride resin molded product having excellent alcohol resistance and low-temperature flexibility. The vinyl chloride resin composition for powder molding contains: (a) a vinyl chloride resin; and (b) a 3-methyl-1,5-pentanediol-sebacic acid polyester that includes a sebacic acid-derived structural unit and a 3-methyl-1,5-pentanediol-derived structural unit. The vinyl chloride resin composition for powder molding is preferably used for powder slush molding.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vinyl chloride resin composition for powder molding comprising: (a) a vinyl chloride resin; and (b) a sebacic acid polyester obtained by thin-film distillation consisting of a sebacic acid-derived structural unit, a 3-methyl-1,5-pentanediol-derived structural unit and a 2-ethylhexanol-derived terminal structure, wherein the (a) vinyl chloride resin comprises vinyl chloride resin particles having a particle diameter of 30 μm or more and vinyl chloride resin fine particles having a particle diameter of less than 30 μm. 2. The vinyl chloride resin composition for powder molding according to claim 1 , comprising not less than 5 parts by mass and not more than 200 parts by mass of the (b) sebacic acid polyester relative to 100 parts by mass of the (a) vinyl chloride resin. 3. The vinyl chloride resin composition for powder molding according to claim 1 , further comprising (c) an additional ester other than a sebacic acid polyester. 4. The vinyl chloride resin composition for powder molding according to claim 1 , comprising not less than 5 parts by mass and not more than 99 parts by mass of the (b) sebacic acid polyester relative to 100 parts by mass of all plasticizer. 5. A vinyl chloride resin molded product obtained through powder slush molding of the vinyl chloride resin composition for powder molding according to claim 1 . 6. The vinyl chloride resin molded product according to claim 5 , used for an automobile instrument panel. 7. A laminate obtained through stacking of the vinyl chloride resin molded product according to claim 5 and foamed polyurethane. 8. The laminate according to claim 7 , used for an automobile instrument panel.
