Latest Patents
Kuroda's latest patents include a process for preparing poly-.alpha.-amino acid particles. This process involves polymerizing an .alpha.-amino acid-N-carboxy anhydride using a polymerization initiator in an organic solvent. The unique aspect of her method is that both the solubility of the .alpha.-amino acid-N-carboxy anhydride and the produced poly-.alpha.-amino acid are 0.1 g/100 ml or less at 25°C. This innovation allows for the easy manufacturing of polyamino acid particles with high molecular weight and small bulk specific gravity. These particles have versatile applications, including use as coating materials for papers, resins, rubbers, and fibers, as well as in cosmetics, diagnostic drugs, chromatography fillers, and encapsulating materials for drugs, fertilizers, and perfumes.
Another notable patent involves the production of solid poly-.alpha.-amino acid particles through an oil-in-water emulsion process. This method allows for the creation of hollow particles by adding a poor solvent for the poly-.alpha.-amino acid and subsequently removing the solvents. The resulting poly-.alpha.-amino acid particles serve as novel raw materials for various applications, including coatings, encapsulation of cosmetics, drugs, agricultural chemicals, and diagnostic reagents.
