Thermoplastic rubbers were designed using renewable resources derived from natural products like corn, mint, tulip and cellulosic biomass. Renewable triblock copolymers such as poly(lactide)-poly(menthide)-poly(lactide) (PLA-PM-PLA), Poly(α-methylene-γ-butyrolactone)-poly(menthide)-poly(α-methylene-γ-butyrolactone) (PMBL-PM-PMBL), Poly(γ-methyl- α-methylene-γ-butyrolactone)-poly(menthide)-poly(γ-methyl- α-methylene-γ-butyrolactone) (PMeMBL-PM-PMeMBL) were synthesized. The polymers were characterized by NMR spectroscopy and size exclusion chromatography. Microphase-separation was determined using small-angle X-ray scattering and atomic force microscopy. Probe tack, peel adhesion, and shear strength tests were adjusted to evaluate the pressure-sensitive adhesive performance of PLA-PM-PLA. The elastomeric mechanical properties of PMBL-PM-PMBL and PMeMBL-PM-PMeMBL were studied by tensile experiments, even at elevated temperature. |
