以2-氰基-2-丁基二硫代苯甲酸酯（CBDB）为可逆加成-断裂链转移（RAFT）引发剂，通过RAFT聚合成功地合成了聚丙烯酸酯和聚甲基丙烯酸酯。使用自动化平行合成器机器人，针对四种丙烯酸酯和四种甲基丙烯酸酯筛选四种不同比率的RAFT与引发剂。通过凝胶渗透色谱（GPC）和气相色谱（GC）监测反应。在此筛选过程中获得的知识用于设计合成的嵌段和无规共聚物含有水溶性和非水溶性单体。从GPC分析与H-1 NMR光谱一起获得的结果证明了设计和制备定义明确的嵌段和无规共聚物的可能性。(c)2005 Wiley Periodicals，Inc.
Poly(acrylate)s as well as poly(methaerylate)s were successfully synthesized via reversible addition-fragmentation chain-transfer (RAFT) polymerizations using 2-cyano-2-butyl dithiobenzoate (CBDB) as RAFT-agent. Four different ratios of RAFT to initiator were screened for four acrylates and four methacrylates using automated parallel synthesizer robots. The reactions were monitored by gel permeation chromatography (GPC) and gas chromatography (GC). The knowledge obtained during this screening was used for the designed synthesis of block and random copolymers containing a water- and a non water-soluble monomer. The results obtained from GPC analysis together with H-1 NMR spectroscopy demonstrate the possibility to design and prepare well-defined block and random copolymers. (c) 2005 Wiley Periodicals, Inc.
