Thermoplastic elastomers (TPEs), which include the elasticity of vulcanized rubber and the thermoplasticity of plastic, have been used in a variety of applications in industry. Among many types of TPEs, styrenic TPEs, poly(styrene-b-butadiene-b-styrene) (SBS) or poly(styrene-b-isoprene-b-styrene) (SIS), are still widely being used in this field. However, these TPEs are polymerized from petroleum-based monomers such as styrene, isoprene, and butadiene. In this regards, an increased interest in the development of sustainable TPEs has been emerged. Accordingly, in this study, lauryl acrylate (LAc) derived from vegetable oils and styrene were polymerized by reversible addition-fragmentation chain transfer (RAFT) polymerization to synthesize sustainable TPE, poly(styrene-b-lauryl acrylate-b-styrene) (SLAcS). On the basis of synthetic results of SLAcS, sustainable TPE with high-Tg glassy block (poly(tert-butylstyrene-b-LAc-b-tert-butylstyrene) (tBSLActBS)) was additionally prepared. |
