Patent number: 8497333Abstract: Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.Type: GrantFiled: November 14, 2011Date of Patent: July 30, 2013Assignees: Hyundai Motor Company, Hyosung Corporation, Desco Co., Ltd.Inventors: Choon Soo Lee, Min Hee Lee, Bong Hyun Park, Jong Hwal Kim, Sung Kyoun Yoon, Byoung Gook Kang, Keun Kyu Lee, Jong Lee
