The introduction of ABS 0212A


Conventionally, a vinyl chloride-based resin has been used as a molding material for calender molding in order to produce adhesive films, bases for a decorative material and the like. However, issues relating to the environment have prompted investigations regarding recyclable alternatives, e.g., an olefin-based resin such as polyethylene and polypropylene, a rubber-reinforced resin such as an ABS 0212A  and an AES resin, and the like.

The objective of the present invention is to provide a thermoplastic resin capable of producing a thin-walled article such as a film, a sheet and a bag stably by extrusion such as calender molding, and of leading to a thin-walled article wherein an undesirable phenomenon due to flow marks generated on the surface is improved and which is excellent in whitening resistance upon bending, and the like, and a method for the production thereof, a molded article and a composite article comprising thereof. The present thermoplastic resin comprises an acryl-based rubbery polymer reinforced resin having a graft ratio of 80% to 170%, a number-average particle diameter of an acryl-based rubbery polymer of 60 to 150 nm, an intrinsic viscosity of a component dissolved by acetonitrile of 0.4 to 0.8 dl/g, a content of a bound cyanidated vinyl compound in the component dissolved by acetonitrile of 20% to 30% by mass, and standard deviation of a distribution of the content of a bound cyanidated vinyl compound measured using liquid chromatography is 5 or less.
