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 Mn. 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 × 10−3. Depending on the molecular weight, PIMA with a large range of Tg from room temperature to higher than 100 °C could be obtained. Furthermore, the treatment of high-Tg 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 (Tg = 116 °C and E′ = 4 GPa).

异山梨醇单丙烯酸酯：生产完全生物基聚丙烯酸酯和热固性材料的可持续单体
异山梨醇单丙烯酸酯（IMA）是通过异山梨醇与丙烯酸反应形成的完全基于生物的单体。从基本的角度看，并作为目前石油基和致癌单体的潜在替代品，了解其在常规自由基聚合过程中的行为至关重要。为此，已经在各种条件下（即不同的溶剂或[IMA] / [Initiator（AIBN）]比率）深入研究了IMA的自由基聚合能力。在所有情况下，都达到M n的平稳期。进行了IMA自由基聚合反应的Mayo方法，确定向单体的转移（C tr M）常数高达1.4×10 -3。根据不同的分子量，具有大范围的PIMA Ť克至高于100℃，从室温可以得到的。此外，用琥珀酸酐处理高T g PIMA可获得高性能的热固性塑料，其热机械性能接近于商业环氧树脂，例如DGEBA基树脂（T g = 116°C，E '= 4 GPa） 。
