Latest Patents

One of Sugiyama's latest patents is for a hard capsule that is primarily made from a polymer or copolymer. This capsule is created by polymerizing or copolymerizing at least one polymerizable vinyl monomer in the presence of polyvinyl alcohol or its derivatives. Unlike traditional hard capsules, this innovative design allows for the filling of a solvent, such as polyethylene glycol, which can accommodate sparingly soluble drug ingredients.

Another significant patent involves a coating composition for polyolefin resins. This invention includes a resin obtained by graft-copolymerizing an α,β-unsaturated carboxylic acid or its anhydride with polypropylene or a propylene-α-olefin copolymer. The process also involves chlorinating the graft copolymer to create an acid-modified chlorinated polyolefin and linking a (meth)acrylic ester to the polyolefin via an ester linkage. This composition and its production process represent a notable advancement in material coatings.
