    摘要： Provided are an inorganic substance powder-filled resin composition that provides excellent mechanical properties, has rich ductility, and allows a molded product having excellent moldability and processability and excellent surface appearance to be produced, and a molded product made of such a resin composition. The inorganic substance powder-filled resin composition includes a thermoplastic resin and inorganic substance powder in a proportion of 50:50 to 10:90 in a mass ratio, in which the thermoplastic resin includes a propylene homopolymer and a propylene block copolymer, and a content of the propylene block copolymer is 10 parts by mass or more and 30 parts by mass or less relative to 100 parts by mass of the propylene homopolymer. Maleic anhydride-modified polypropylene may further be included in an amount of 0.5 parts by mass or more and 3.0 parts by mass or less.

    摘要： A disclosed adhesive contains non-functionalized lignin and natural rubber latex in an aqueous medium having pH ≥9. The aqueous medium may further include 0.1% to 3% by mass of at least one alkali selected from the group comprising ammonium, sodium, calcium, magnesium, potassium hydroxides, and a salt such as sodium bicarbonate. A mass fraction of lignin may be between 0.1 and 20%, and the adhesive may include cellulose particulate material having sizes in a range between 5 μm and 5 nm, and/or fibrillated cellulose, and/or crystalline cellulose. The cellulose may have a dry mass fraction between 0.05 and 5%. A method of manufacturing may include forming a mixture by adding solid, non-functionalized lignin to a colloidal dispersion of natural rubber latex in an aqueous medium having pH ≥9, and stirring the mixture for a period of 10 to 20 minutes at room temperature and pressure.
