Patent number: 8124703Abstract: Disclosed are a maleimide-?-alkylstyrene-based, heat-resistant bulk tetrapolymer and a preparation process thereof. More specifically, disclosed are a bulk tetrapolymer, comprising 5-60 wt % of an N-substituted maleimide monomer, 10-70 wt % of an ?-alkylstyrene monomer, 5-50 wt % of an unsaturated nitrile monomer and 3-50 wt % of an aromatic vinyl monomer, as well as a continuous bulk polymerization process for preparing the same. The disclosed bulk tetrapolymer has a weight-average molecular weight (Mw) of 70,000-300,000 and a glass transition temperature of 150-200° C., shows excellent high-temperature thermal stability and heat resistance and a remarkably low melt viscosity, and thus is excellent not only in processability, but also in productivity, processability, moldability and blendability, when it is blended with other resins. Also, the continuous bulk polymerization process is equipped with a devolatilizer and enables the bulk tetrapolymer to be produced at low cost and high efficiency.Type: GrantFiled: December 2, 2006Date of Patent: February 28, 2012Assignee: Korea Kumho Petrochemical Co., Ltd.Inventors: Dong Cheol Sohn, Sup Joo Lee, Byung Yoon Ahn

Patent number: 8101670Abstract: The present invention discloses polymers prepared through the Diels-Alder reaction with benzoxazine groups in their main chains. Moreover, polymers with high molecular weight could be successfully prepared via this method. Furthermore, the mentioned polymers are able to undergo crosslinking reaction by heat treatment. Heat energy causes the ring-opening reaction of benzoxazine in polymer main chains to undergo crosslinking reaction, and cross-linked polymers are thereby formed with great flexibility and high crosslinking degree.Type: GrantFiled: April 21, 2009Date of Patent: January 24, 2012Assignee: Chung Yuan Christian UniversityInventors: Ying-Ling Liu, Ching-I Chou
