Abstract: Disclosed is a polylactic acid/polycarbonate resin composition including (A) a mixed resin including (a1) a polycarbonate resin and (a2) a polylactic acid resin, and (B) a modified acrylic-based resin, and a molded product made using the same.

Abstract: An environmentally-friendly polylactic acid resin composition includes (A) a mixed resin including (a1) a polylactic acid (PLA) resin and (a2) a polycarbonate resin, and (B) a compatibilizer capable of forming a stereo-complex with the polylactic acid resin. According to the present invention, the polylactic acid resin composition is environmentally-friendly and has excellent appearance and improved welding impact strength, as well as improved mechanical strength and heat resistance. Accordingly, it can be used for manufacturing various molded products requiring heat resistance and mechanical strength, for example electronic parts, office machines, miscellaneous goods, and the like.

Abstract: The present invention relates to a polylactic acid resin composition. The composition includes about 25 to about 80 parts by weight of a polylactic acid resin, (B) about 20 to about 75 parts by weight of a polycarbonate resin, and (C) about 0.01 to about 5 parts by weight of a chain extender including an amine group, based on about 100 parts by weight of (A)+(B). The polylactic acid resin composition of the present invention is environmentally-friendly and has excellent hydrolysis resistance and simultaneously improved mechanical strength and heat resistance, and accordingly can be used for manufacturing various molded products requiring heat resistance and mechanical strength, for example vehicles, machine parts, electronic parts, office machines, miscellaneous goods, and the like.

Abstract: Disclosed are a polylactic acid resin composition that includes (A) about 10 to about 80 wt % of a polylactic acid resin; (B) about 5 to about 50 wt % of a rubber modified vinyl-based graft copolymer; (C) about 10 to about 80 wt % of a vinyl-based copolymer; and (D) about 5 to about 75 wt % of poly(meth)acrylic acid alkyl ester, and a molded product made using the same.

Abstract: Disclosed are a polyhydroxy alkanoate resin composition including (A) a polyhydroxy alkanoate resin and (B) a vinyl-based copolymer resin including (B-1) a copolymer including two or more monomers comprising an aromatic vinyl monomer, an unsaturated nitrile monomer, an acryl-based monomer, or a combination thereof; and (B-2) a rubber-modified vinyl-based graft copolymer and a molded product fabricated using the same.

Abstract: Disclosed is a natural fiber-reinforced polylactic acid resin composition that includes (A) a first polylactic acid resin; and (B) a natural fiber surface-treated with a second polylactic acid resin. The second polylactic acid resin can include a different isomer from the first polylactic acid resin, or alternatively, when measured under isothermal conditions after quenching from about 240° C. to a crystallization temperature, a spherulite crystal is first formed at a surface of the natural fiber and the growth rate at the surface is faster than at other positions. A molded product made using the natural fiber-reinforced polylactic acid resin composition is also disclosed.
