是化学品吗？没找到，只找到这个 BTCT [=bithermal caloric test]双温冷热试验,双温热量试验 送你一个常用有机化合物的缩写与结构 http://www.namipan.com/d/%e5%b8% ... 172deef8d6052610900 [ Last edited by yanjianfeng on 2009-7-9 at 11:05 ] |

ＢＴＣＴ Benzyl thiophene-2-carbodithioate Reversible addition-fragmentation chain transfer polymerization of styrene using a novel thiophene dithioester as the reversible addition-fragmentation chain transfer agent Nianchen Zhou 1 2, Lude Lu 1, Jian Zhu 1, Xujie Yang 2, Xin Wang 2, Xiulin Zhu 1 *, Zhengbiao Zhang 1 1School of Chemistry and Chemical Engineering, Suzhou University, Suzhou 215006, China 2Materials Chemistry Laboratory, Nanjing University of Science and Technology, Nanjing 210094, China email: Xiulin Zhu (xlzhu@suda.edu.cn) *Correspondence to Xiulin Zhu, School of Chemistry and Chemical Engineering, Suzhou University, Suzhou 215006, China Funded by: National Nature Science Foundation of China; Grant Number: 20574050 Science and Technology Development Planning of Jiangsu Province; Grant Number: BG2004018 Suzhou City; Grant Number: SG0413, SSZ0419 Nature Science Key Basic Research of Jiangsu Province for Higher Education; Grant Number: 05KJA15008 Specialized Research Fund for the Doctoral Program of Higher Education; Grant Number: 20040285010 Keywords functionalization of polymers • living polymerization • polystyrene • radical polymerization Abstract Benzyl thiophene-2-carbodithioate and 2-methyl-2-(4-methylcyclohex-3-enyl)propyl thiophene-2-carbodithioatewere synthesized. The reversible addition-fragmentation chain transfer polymerizations of styrene with benzyl thiophene-2-carbodithioate and 2-methyl-2-(4-methylcyclohex-3-enyl)propyl thiophene-2-carbodithioate as chain-transfer agents and with 2,2-azobisisobutyronitrile as an initiator were carried out. The polymerization kinetics were investigated. An ab initio calculation method was used to explore the differences between benzyl thiophene-2-carbodithioate and benzyl benzodithioate. The structure of the obtained polymers was characterized with 1H-NMR. Chain-extension experiments of the obtained polymer with styrene were carried out. © 2007 Wiley Periodicals, Inc.
