Latest Patents

One of Lee's latest patents is for a high-viscosity biodegradable aliphatic-aromatic polyester copolymer that exhibits excellent hydrolysis resistance. This innovative copolymer has a carboxyl end group (CEG) content of 15 mg KOH/g or less, a z-average molecular weight (Mz) to a number average molecular weight (Mn) ratio of 3 to 15, and a melt index (MI) of 5 g/10 min or less, measured under specific conditions. The method of preparing this copolymer involves adding a chain extender and an anti-hydrolysis agent to an aliphatic-aromatic polyester pre-copolymer over time, allowing for a significant rise in viscosity and improved hydrolysis resistance. Another notable patent involves a method for producing a substrate, which includes exposing and developing a photosensitive resin composition layer on a substrate base layer to create spacers. This method enables the uniform formation of spacers with adjustable heights according to desired cell gaps.
