Accession number: 201444132445 Title: Rheological properties of polycarbonate/methylmethacrylate-butadiene-styrene copolymer blends Authors: Jia, Baoshan1, 3 Email author bsjia@163.com; Bai, Fuchen2 Author affiliation: 1 Department of Materials Science and Engineering, Changchun University of Science and Technology, Changchun, China 2 Polymer Engineering Laboratory, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun, China 3 Quality Management Department, Changchun University of Science and Technology, Changchun, China Corresponding author: Jia, Baoshan Source title: Gaofenzi Cailiao Kexue Yu Gongcheng/Polymeric Materials Science and Engineering Abbreviated source title: Gaofenzi Cailiao Kexue Yu Gongcheng Volume: 30 Issue: 9 Issue date: September 1, 2014 Publication year: 2014 Pages: 89-92 Language: Chinese ISSN: 10007555 CODEN: GCKGEI Document type: Journal article (JA) Publisher: Chengdu University of Science and Technology Abstract: The blends of polycarbonate and methylmethacrylate-butadiene-styrene copolymer (PC/MBS) were obtained by a twin-screw extruder. The effects of temperature and MBS content on the rheological properties of as-prepared blends were studied. The results show that the processing performance of PC was significantly improved with the addition of MBS. The apparent viscosity of the PC/MBS blends decreases with increase of temperature. When the mass fraction of MBS is below 15%, the apparent viscosity and visco-flow activation energy of PC/MBS blends decrease with increase of MBS content. At the same time, the non-Newtonian index increases. The PC/MBS blends with the best rheological behavior can be obtained when the mass fraction of MBS is 15%. Then the rheological behavior of PC/MBS blends would deteriorate with increase of the mass fraction of MBS.
