Patent number: 8039533Abstract: Disclosed are a synthetic resin composition for use as building materials such as window frames, as well as a product manufactured using the same. More particularly, the synthetic resin composition comprises a tetrapolymer of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyanide monomer and a styrene-vinyl cyanide copolymer having a high molecular weight and a high degree of dispersion. Unlike products manufactured using prior polyvinyl chloride (PVC), building material such as window frames manufactured using the synthetic resin composition are recyclable, and thus can contribute to a reduction in the generation of hormone-disrupting chemical dioxin, which is released in the burning thereof. Also, the resin composition can be manufactured into products having excellent properties of weather resistance and colorability without using environmental pollutants such as cadmium stearate or lead stearate, which are used as thermal stabilizers.Type: GrantFiled: October 13, 2010Date of Patent: October 18, 2011Assignee: Korea Kumho Petrochemical Co., Ltd.Inventors: Jang Hyun Choi, Joo Yub Ho, Seung Kyu Lee, Yun Hwan Kim
