Isosorbide monoacrylate (IMA) is a fully bio-based monomer formed by the reaction between isosorbide and acrylic acid. From a fundamental point of view and as a potential substitute for the current petro-based and carcinogenic monomers, it is crucial to understand its behaviour during a conventional radical polymerization. To this end, the radical polymerizability of IMA has been investigated in depth under various conditions (i.e. different solvents or [IMA]/[Initiator(AIBN)] ratios). In all cases, plateaus are reached for M-n. The Mayo method of IMA free radical polymerization was carried out and the transfer to monomer (CtrM) constant was determined to be up to 1.4 x 10(-3). Depending on the molecular weight, PIMA with a large range of T-g from room temperature to higher than 100 degrees C could be obtained. Furthermore, the treatment of high-T-g PIMA with succinic anhydride leads to a high-performance thermoset featuring thermomechanical properties close to those of commercial epoxy resins such as DGEBA-based resins (T-g = 116 degrees C and E' = 4 GPa).
