Polymer blends with self-healing properties using humidity as a stimulus were prepared by mixing two polymer resins containing respectively low concentrations of 4-vinylphenylboronic acid (VPBA) and glycerol monomethacrylate (GMMA). The polymer resins were mostly made from bio-derived monomers isobornyl methacrylate (IBOMA, from terpenes) and C13 methacrylic esters (C13MA, from natural oils) to tune the thermal properties with low concentrations (2 to 15 mol% in feed) respectively of GMMA or VPBA in 1,4-dioxane at 90 °C. The VPBA and GMMA units form dynamic covalent boronic ester bonds to introduce self-healing in presence of humidity at ambient temperature while increasing the chemical and heat resistance of polymer blends. Polymer blend I (29 wt% VPBA-containing polymer with 2 mol% VPBA (T_g = 4.9 °C)) in a terpolymer with 15 mol% GMMA (T_g = −0.4 °C)) and polymer blend II (a 29 wt% blend of a VPBA-containing polymer with 5 mol% VPBA (T_g = −13.2 °C)) in a terpolymer with 15 mol% GMMA (T_g = −0.4 °C)) recovered up to 87% of the stress at break after breakage in 10 days and healed the scratches in 12 days at ambient temperature and relative humidity. The polymer blends are also recyclable and can be easily reprocessed at 80 °C within 50 min.

通过混合分别含有低浓度的4-乙烯基苯基硼酸（VPBA）和单甲基丙烯酸甘油酯（GMMA）的两种聚合物树脂，来制备利用湿度作为刺激物具有自愈特性的聚合物共混物。聚合物树脂主要由生物来源的单体甲基丙烯酸异冰片酯（IBOMA，来自萜烯）和C13甲基丙烯酸酯（C13MA，来自天然油）制成，以分别在低浓度（进料中为2至15 mol％）下调节热性能。或VPBA在90°C下的1,4-二恶烷溶液中。VPBA和GMMA单元形成动态的共价硼酸酯键，可在环境温度下在湿度存在的情况下引入自愈作用，同时提高聚合物共混物的耐化学性和耐热性。聚合物共混物I（29 wt％含VPBA的聚合物与2 mol％VPBA（T _g = 4.9°C））与15 mol％GMMA（T _g  = -0.4°C））和聚合物共混物II（含VPBA的聚合物与5 mol％VPBA的29 wt％的共混物（T _g  =-在含15 mol％GMMA的三元共聚物中（13.2°C））（T _g  = -0.4°C））在10天内断裂后可恢复高达87％的断裂应力，并在环境温度及相对温度下12天内修复了划痕湿度。聚合物共混物也是可回收的，并且可以轻松地在80°C下于50分钟内进行再加工。
