ABA triblock copolymers consisting of glassy A block and rubbery B block normally exhibit properties of thermoplastic elastomers (TPEs). However, commercial ABA triblock copolymers usually comprise ‘petroleum-based’ monomers such as styrene, butadiene, and isoprene. In this regards, the ‘sustainable’ TPEs are actively being investigated. Therefore, in this study, lauryl acrylate (LAc) derived from fatty acids was introduced as rubbery block to replace petroleum-based butadiene or isoprene. Moreover, 1−adamantyl acrylate (AdAc) was used as glassy block to increase upper glass transition temperature. The synthetic results and characterizations of PAdAc-b-PLAc-b-PAdAc will be discussed in detail.
