摘要：

We present the controlled radical polymerization of vegetable oils, e.g. soybean oil, with styrene into thermoplastic elastomers. We have discovered that under certain reaction conditions controlled radical polymerization, such as RAFT, limits the number of initiation sites and drastically reduces the rate of chain transfers and termination reactions. This discovery introduces the capability of producing customized chain architectures such as block copolymers (BCPs) from vegetable oils. Here we report the synthesis of poly(styrene-b-AESO-b-styrene) (PS-PAESO-PS) triblock copolymers with properties similar to petroleum based thermoplastic elastomers.
