Latest Patents

Oh-Jin Kwon holds a patent for a "Transparent, rubber-modified styrene copolymer." This invention relates to a method of preparing rubber-modified styrene copolymer resin that exhibits excellent transparency and impact resistance. The method involves graft-copolymerizing styrene monomer and (meth)acrylate monomer in the presence of a block or random styrene-butadiene copolymer. This copolymer contains 30-50% of styrene skeleton content and has a viscosity of 20-40 cp in a 5% toluene solution at 25°C. The resulting transparent resin incorporates rubber particles with a double structure, providing both excellent transparency and impact resistance, along with good gloss.
