品として実用に供されている。2. Description of the Related Art The addition of inorganic fillers to thermoplastic resins
Often used for the purpose of improving the mechanical properties of resins, reducing costs and environmental measures by saving plastics, and reducing the load on incineration facilities by reducing the calories burned when incinerating waste plastics, such as polyethylene and polypropylene. It is practically used as a film or molded product by mixing calcium carbonate or talc with a suitable polyolefin, forming a sheet, or molding.

ても、機械的な混合であって化学変化が伴わないだけ
に、無機充填剤の分散不良により、均一なフィルムや成
形品が得難く、機械的な性質が低下する問題がある。[0003] However, even if an inorganic filler is added to a thermoplastic resin, it is difficult to obtain a uniform film or molded article due to poor dispersion of the inorganic filler because of mechanical mixing and no chemical change. There is a problem that the mechanical properties deteriorate.

Further, in some cases, the inorganic filler may float out in a powder form on the surface of the resin, resulting in a contaminating film or molded product.

However, the compatibility with the resin is not so good, and the polymer tends to migrate to the surface with time and cause stickiness.
